I think they should be fine. I have 5 (pygmy, Eibli, Flame, Coral Beauty and Potter's) of the centropyge angels in my 65 gallon and they're doing fine. Just make sure u introduce the smaller of the pygmy angel first or introduce them at the same time. Also, make sure you have a ton of rocks for them to hide.
