I agree with Nessa that the barred rock is a roo. I also think the red one is a roo too - it looks like a production red or hatchery RIR to me ( you can see pictures of mine on my BYC page).
The red & white on is a red sexlink pullet. The black one is either a black australorp or a black sexlink pullet. Are there any brown feathers on its chest? If not, it's probably the BA - if it does have brown feathers, I think it's a BSL.
