I don’t think the angel ranks and most of the names for them are in the Bible, but I think that is long time Christian and Jewish tradition. The living creatures and their spirits are probably distinct from the seraphim though as they are much more wings and less eyes and rings.
I think I heard that these are Seraphim, which are like the highest rank of angel, and lower-rank angels look more traditional/humanoid
