Sorry, but better photos are needed - photos more up-close of their backs and faces.
Black one is a male though, he has male-specific feathers coming in.
So is the little red and gray one in the last photos.

How old are they? And I agree, need better pictures from the side

The black one and the brown one with gray/blue highlights are males.

The gray one is female. The other brown one is probably female, too.

Those are best guesses based on these pictures.
