Angel's gender identity is pretty ambiguous, so this is a post about that.
The stage directions use he, probably in reference to the actor more than the character.
Today 4 U:
Collins: And you should hear her beat.
Santa Fe
Collins: Sing it, girl.
La Vie Boheme
Collins: Angel Dumott Schnard will model the latest fall fashions from Paris while accompanying herself on the ten gallon plastic pickle tub.
I'll Cover You: Reprise
Mimi it was one of her favorite holidays [...] that skinhead was bothering her and she said she was more of a man than he'd ever be and more of a woman than he'd ever get.
Mark: a drag queen[...] and he... she just offered to escort them out of Alphabet City
Maureen, interestingly, uses "you" in this scene.
Halloween
Mark: And Collins choose that phone booth/Back where Angel set up his drums?
Goodbye Love
Collins: I can't believe he's gone.
Roger: His death is in vain.
