A large number of the Goetic Demons are understood to be fallen angels, some of which have stated their former angelic choir to humans, and even hope to return to the heavens.
Agares- Order of Virtues
Aim
Alloces
Amdusias
Amy- Order of Powers and Angels
Andras
Andrealphus
Andromalius
Asmodeus- Order of Thrones or Angels (Honestly, Asmodeus shouldnt be on here because he was never an angel, he was born from a human and an angel. But some sources are insistent on claiming he’s somehow a fallen angel.)
Astaroth- Order of Thrones (more likely to be a demonized god than an actual fallen angel)
Bael (same case as Astaroth)

Had! The manifestation of thy will
That which is of perfection shall come to you
Fear and loathing dissipate
Pity and longing evaporate
The essence of dreams has entered reality
No longer shall ye gaze into the abyss
Forego all woes, you were meant to live in bliss
A bolt of lightning strikes the mind, illuminating the eye
Jewels of the cosmos form upon your soul
And both the inner and outer world completes a rotation
As above, so below
