Castiel, Uriel, Balthazar and Hester were all low-ranking angels.

I'd like to think of Joshua as being just below a Seraphim's power, as he gets to talk with God

Zachariah and all of Raphael's army, I'd say, were Seraphim

The Cherubs we've already seen

I'd say Anna was an extremely high angel, as she was Castiel's captain, and Inias would probably be as powerful as her, due to the assumption that he has taken control of the angels upon Hester's death

And then the Archangels, Michael, Lucifer, Gabriel, Raphael

I'd say the number of wings increase depending on angelic ranking. Cas and his Garrison have two because they're common soldiers. Cherubs have four, Seraphs have six. Anna probably had six or something as she was high up. I'd also say Archangels probably have eight wings or something, that would be the highest number
