- God (formerly) - As their Creator, he was their Father and King, and governed the Celestial race singlehandely, but upon his retreat/disappearance, Michael, his mightiest warrior, took command over the Angels.
- Michael (formerly) - When God left, Michael took control of Heaven. With him being in the Cage, he effectively has no say on the Host of Heaven anymore.
- Raphael (formerly) - He wanted the Host of Heaven to bow down to him, and as Castiel declared Civil War, it is unknown if they ever took the pledge.
- Castiel (temporarily) - Empowered by all the souls of Purgatory, Castiel, for a time, was able to rule Heaven with ease.
- Naomi (presumably, formerly) - Although it is stated by Metatron that Naomi is just a leader of one of multiple factions battling for control over Heaven.
- Michael - God's oldest and mightiest Angel. He ruled in God's place for at least 6 millennia. But, since his imprisonment, he is no longer its leader.
- Lucifer (rebelled) - Before disobeying God, Lucifer was an extremely powerful force in God's heavenly alliance and his most beloved Angel. But since his fallout, he isn't part of the host anymore.
- Raphael - (deceased) Before Lucifer's banishment, Raphael was an executive angel, whose initial designated ranking is unknown, although it is known that he watched over prophets. But once Lucifer fell, Raphael fell directly under Michael. He took over for Michael after he was sent to Lucifer's Cage and waged a civil war with Castiel for control of Heaven that ended with Castiel killing him and his followers.
- Gabriel - (deceased) He was a high-executive in the establishment, however his actual ranking is unclear. He was God's greatest messenger before he left heaven and masqueraded as the trickster Loki on Earth.
- Zachariah (deceased) - He, being a seraph, was an angel of high esteem, and largely recognized for his accomplishments and achievements, being a six millennia old angel. After his constant failure to secure Dean, Michael kicked him out, but decided to give him one more chance. However, Dean killed him.
- Castiel (promoted) - After being resurrected by God for a second time, he was promoted to the rank of Seraph and gained great power and influence over the angels of Heaven. He used this to start a civil war against Raphael that ended when Castiel declared himself the new God and smite Raphael and his followers. Castiel was ruler of Heaven for a time as the new God, but eventually gave up the power and died as a result of possesion by the Leviathans. Even though he was resurrected again, he has chosen not to return to Heaven and has essentialy renounced his role in Heaven, though he remains a Seraph and as such retains all of his powers. Castiel was the captain of his garrison that succeded Anna. He was for the most part a very obedient/committed angel. But ever since he banished his superior, Zachariah, he was unable to return to Heaven.
- Naomi (deceased) - Angel of high ranking who exists in a part of Heaven that not many have been to. Metatron described her to be one of the key players in the power vacuum left by the Apocalypse and Castiel's self-proclamation as the new God. She could easily exert control to lower angels and even alter their memory. She was able to make Castiel answer her questions despite him being a Seraph and able to order an incursion into Purgatory to rescue him that cost many angels their lives. She had several angels working under this division.
- Ion (deceased)
- Esper (deceased)
- Unnamed angel with female appearance (Goodbye Stranger)
- Anna (deceased) - She was originally a garrison leader, over Castiel, Uriel, and Balthazar. But when she fell and removed her Grace, that position was revoked. She eventually did reclaim her Grace, and Michael eventually "fired" her for trying to kill Mary Winchester before Sam and Dean were born.
- Uriel - (deceased) He was below Castiel. He was noted as a Specialist by Castiel, the meaning of which is unclear. However, he was a considerably powerful angel given his type. Killed by Anna to save Castiel after being revealed to be a Lucifer loyalist.
- Hester (deceased) - Though she is only an average angel from Castiel's garrison, Hester assumed command of the Heavenly Host when Castiel and Raphael both died. Killed by Meg to save Castiel.
- Balthazar - (deceased) Balthazar was a dear old and good friend of Castiel, fighting alongside him in the Host. Balthazar was "a great and honorable soldier", according to Castiel. At the first chance Balthazar got, however, he quit the Host, involving himself in Earth's song; wine, thievery, etc. At one point after Michael and Lucifer were imprisoned, he moonlighted as a Crossroads Demon on Earth. After helping Castiel a few times, he rejoined the host. He was killed by Castiel for betraying him.
- Rachel - (deceased) Her official ranking is unknown, however when Castiel rebelled, and formed his own battalion of angels, Rachel was his lieutenant and his friend. She was killed by Castiel in self-defense when she learns of his plans and attacks him.
- Inias (unknown) - Average ranking angel from Castiel's former garrison who seemed to act as Hester's second in command. More forgiving of Castiel for his actions and more friendly to humans. Took over Hester's role after she died, but it is unknown if he remains alive as most of the angels from Castiel's garrison were wiped out by the Leviathans.
- Cupids - A special class of angels, they rank below other members of the Host. They are tasked in causing specific couples and bloodlines to meet and mix, depending on Heaven's interests. John Winchester and Mary Campbell pairing was a high priority for the Cupids.
- Secretarial angels - described by Metatron as "run-of-the-mill" angels who functioned separately from soldier angels and intelligence angels
- Virgil - "Weapons Keeper of Heaven". Sometime after his creation, he was put in charge of all of Heaven's weapons. He was considered to be the "nastiest" angel under Raphael's command. He is now trapped in the alternate Earth.
- Metatron - "Scribe of God". An angel who was selected from the secretarial pool to be elevated as the Scribe of God. He left Heaven when the Archangels took over and cut himself off completely but retains all of his powers. He was recently responsible for banishing every angel to the Earth.
- Joshua - He was significantly lower than most other angels, however he has an important occupation, in cleaning/monitoring God's Throne Room, which appears as a garden, and he was the only one who God speaks to directly, albeit not face to face.
For the first time in 2000 years, angels walked the earth. They sent angels to save the Dean Winchester from hell and to keep him from breaking the first of the 66 seals that would free Lucifer from his cage. They fought several skirmishes against demons, witches and other agents of Lilith. The host was also concerned with Sam's growing reliance on demon blood, and warned Dean that if he did not stop his brother, they would.
They sought to kill Anna Milton, a former garrison leader who chose to remove her grace to become human, to prevent her from divulging the plans of the angels and to prevent demons from taking hold of her and her ability to hear angels. Anna Milton eventually took her grace back to aid the Winchesters and Ruby in their fight against Alastair. She began to convince Castiel that the orders to usher the apocalypse was not God's command.
During the battle for the seals, several angels were slain. In an effort to determine who was causing the deaths, as well as to halt the progress of hell in breaking open the seals, they captured Alastair. The angels forced Dean to torture information from the demon, who denied the accusations. It was later revealed that they died from the hands of their brethren, who were led by Uriel. The rogue angel wished to free Lucifer, because like the archangel, Uriel believed humans to be below angels, and only saw themselves as the perfect creation of God. Moments before Uriel was about to kill Castiel, Anna arrived and killed Uriel herself.
The revelation of Uriel's betrayal prompted Zachariah, the superior of the lower angels, to come down to earth. He convinced Dean about his purpose and the role he would play in the apocalypse. In truth, the higher angels actually wished to let the seals be broken so that their leader, Michael could finally vanquish Lucifer and usher paradise on earth. This ulterior motive guided most of the actions of the host, even threatening the prophet Chuck not to warn Sam and Dean of the impending result of the battle for the seals. Zachariah had Castiel captured and taken back to heaven for rehabilitation. Castiel went back to earth strictly adhering to Heaven's orders and had Anna Milton taken to Heaven as well. Zachariah and his angels also prevented Dean from reaching Sam in time before he could kill Lilith, whose death meant the final seal would be broken.
Castiel finally decided to act on his own accord and allowed Dean to get to Sam. Chuck had a vision of this and noted it was not supposed to happen. This prompted Raphael, who was tethered to the prophet, to arrive and to smite Castiel, who attempted to hold the archangel off. Castiel, however, stood no chance and was killed.
The host, led by Zachariah, scrambled to secure the Michael Sword. The prophet Chuck knew of the location, which he revealed to Dean to be inside John's Lock Up. Zachariah waited for Sam and Dean inside the locker, and revealed that the Michael Sword actually referred to Dean being the archangel's true vessel, and the prophecy Chuck shared was actually falsely implanted to lead the brothers to the seraph. Dean, however, would not agree to being used as a vessel. This infuriated Zachariah, who threatened to harm the Winchesters, until Castiel's arrival prevented the seraph from doing so. To protect the Winchesters, Castiel carved enochian sigils on the ribs of the brothers, which hid them from all angels in existence, including Michael and Lucifer, who were both actively trying to reach their true vessels.
The Heavenly Host spent most of their efforts trying to secure the Winchesters, albeit to little effect. They continued to fight battles against demons, and other forces of hell, including the antichrist or the cambion, which could wipe out the Heavenly Host with a thought. Desperate, they resurrected Adam Milligan, half-brother of the Winchesters, as a contingent vessel for Michael. Sam and Dean convinced Adam to refuse, although the machinations of Zachariah proved to be effective. Although killed by Dean, Zachariah was able to secure consent and summon Michael. The archangel missed his true vessel, but decided to trap and take Adam instead.
Eventually, Lucifer secured a consent from Sam, and met with Michael to begin their battle. The rest of the host did not intervene, as they believed Michael was more than capable to defeat his brother, and that it was Michael's destiny to do so. Castiel, Dean and Bobby attempted to prevent the fight by causing diversions. Castiel banished Michael with Holy Fire, which angered Lucifer, who then killed Castiel. However, this bought enough time for Dean to talk to Sam and convince his brother to overpower Lucifer, moments before Michael returned. Sam and Dean managed to trap the archangels in Lucifer's Cage, effectively averting the apocalypse, and leaving the heavenly host leaderless. A newly resurrected Castiel was elevated as a seraph returned to Heaven to ensure order.
Shortly after the Apocalypse was stopped, Raphael called an assembly of the Host, in which angels would either align with him, or die. The archangel planned to restart the apocalypse. This drew opposition from Castiel, who started promoting free will among angels. Raphael did not like Castiel's insurrection and made it clear by demonstrating his power. Castiel then struck a deal with Crowley to prevent the archangel from pursuing his plans to restart the apocalypse. Crowley loaned Castiel with enough souls to challenge Raphael. At that point civil war has erupted, with angels taking either of the opposing sides.
Balthazar, a rogue angel, has stolen Heaven's weapons, which were sought by both of the belligerents. Balthazar loosely aligned himself with Castiel, which allowed the seraph to force even the archangel Raphael to flee.
Castiel, who sought more power from souls ordered Balthazar to save the Titanic, thus creating several thousands of souls to boost their power. However, this drew the ire of Atropos, who was willing to let the planned future go but was determined to keep the past the way it was supposed to be. After a stalemate, Castiel was forced to order Balthazar to correct the flow of events by sinking the Titanic again.
Meanwhile, as part of the deal with Crowley, Castiel secretly assisted in torturing monsters to locate Purgatory and use the monster souls to power themselves. This eventually became known to his lieutenant Rachel, who saw the partnership as unclean. She was distressed that she put her faith in someone who would work for a demon and attempted to kill Castiel. The fight between the two resulted into the death of Rachel.
Crowley and Castiel eventually discovered how to open Purgatory, but in the last minute, Castiel removed Crowley from the deal, claiming all the souls for himself. The angered demon then switched alliances and was given the protection of Raphael, who forced Castiel to surrender. However, the seraph tricked both the demon and the archangel and managed to absorb the souls from Purgatory. He then let the demon escape a few moments before smiting Raphael, effectively ending the war and the plans to restart the apocalypse.
After absorbing every soul in Purgatory, along with the Leviathans, God's oldest creation, Castiel, returned to Heaven and slaughtered any remaining angel who aligned with Raphael during the civil war. This drastically reduced the number of the heavenly host, although this would not be the last massacre that the host would suffer from.
Later, two angels from his garrison, specifically Hester and Inias, came to Earth to secure the Prophet, Kevin Tran. Hester was killed, and Inias returned to Heaven, bringing the rest of the garrison under his leadership. Castiel revealed that his garrison and all the angels who were posted on the Earth were either hiding or dead as the Leviathans might have killed them all. It is unknown if any of the garrison survived or if Heaven has sent a new garrison to watch the Earth now that the leviathans are leaderless.
Heaven was still in disarray and heavily factionalized, with several angels vying for control. A group of angels under the command of the mysterious angel Naomi rescue Castiel from Purgatory. The incursion cost many angels their lives, but it was successful. Naomi later summoned Castiel to her and ordered him to report in to her on the Winchesters from time to time and to aid them in any way they need. Naomi's primary goal was to secure the Angel Tablet and to help the Winchesters close the gates of Hell.
Castiel successfully located the Angel Tablet but was released from Naomi's control upon his contact with the tablet. He fled and took the tablet with him, prompting Naomi to locate Castiel.
Metatron, the Scribe of God who was forced to exile himself from Heaven to protect the Words of God, was later located by the Winchesters. He helped the Winchesters in their goal to seal the gates of Hell. At the same time, he convinced Castiel that Heaven also needed to be shut so that angels could settle their disputes against each other and prevent their quarrels from bleeding into earth. He aided Castiel in completing the first two trials. However, before Castiel could finish, he was abducted by Naomi and her angels.
Naomi attempted to uncover Metatron's thoughts and discovered the scribe was actually working on a plan of vengeance against all the other angels. The trials he set Castiel to were actually part of a spell to banish all angels from Heaven. Naomi immediately conveyed this to Castiel, who was wary of Naomi, but was willing to listen. Castiel travelled to Heaven only to find Naomi dead. He was then incapacitated by Metatron, who removed the seraph's grace and turned him into a human, thus completing the spell. Not long after, the entire Host of Heaven save for Metatron was seen falling down onto earth, losing their wings in the process.
