Hi! The one on the left in the first pic is most likely a red breasted hen. The red breasted roos are much darker, there is no mutation giving the males that color, but it could still start to grow darker feathers and turn out male - not very likely though.
The one in the middle seems a bit lighter than a normal wild colored though I'm not quite sure what mutation causes it. Again, I'd say it's most likely female, the males are usually darker - but it can change.
As Sean says, a white patch on the throat usually indicates the bird is male, but only a full pattern of white and black stripes are a certain sign of the bird being male and as far as I can tell none of yours have that. The one on the right in the first pic seems to be getting blue breast feathers though, meaning it is pretty certainly a male - possibly wild colored split to tuxedo or something like that, causing the strange white throat patch.
The one in the back corner in the second pic I dare not really guess anything about, but I'd love to see more pics of it, it seems to have a very interesting color.
