The stage they're in depends on how much light your friend's giving them. If he has them on a 24/0 (meaning 24 hours of light with 0 hours of dark) light schedule they're still vegging, if he has them on 12/12 (12 hours light, 12 hours dark) then they're flowering.
I can't tell if the plants in those pics have any pistils (white hairs) but you said that those aren't even pics of the actual plants you're asking about so....do the plants have any pistils?
