Caruncles showing at that age I would have to say the White one is a Boy! 
Can you post a few more pictures of the other two? Looks like they might be a boy & girl but it's hard to tell.
Also, the wing tips on the darkest one look to be sticking out a little 'strangely', are they growing correctly or do they seem to be turning outward?
It's normal for babies wings to droop some when the flight feathers are coming in because of extra weight from the blood there and muscle having to develop more, but if they're turning outward I would worry about Angel Wing.
