The gargoyle-like demons are Nabassu, though whether they're at the juvenile stage or much more dangerous mature stage you're unable to tell from what you saw. They're known to have a life-draining gaze that turns killed victims into ghouls, and they're more familiar with mortals than most demons due to spending their juvenile stage on the Prime, feasting on souls until strong enough to return to the Abyss.
The round glowing ones are Solamiths, demons of gluttony who eat souls and then process them into soulfire, which they can tear from their gut and throw at foes or release in a burst against any creature attacking them.
Gabriel: The demons are flying at a run, so unless you spend your second prep round's actions catching up, you can't reach them.
