What breed(s) and gender are these chicks?

I bought a box of mixed chicks at an auction last week and was hoping someone could guess on the breeds. I have no idea on age. Some of the pics are a little blurry.
#1

#2

#3

#4 did not get a good body shot on this one but she? is all white with pink legs and has some feathers that stick up a bit on the top or her head and cheeks

They look like BA crosses... They look like crosses of something anyway.
