Anyone interested in help/guessing

[Chickies AK]

Hi,
I am new to the group and new to chickens.
I have a straight run of 8 chicks from my daughter’s class and am trying to tell what they are (thoughts on both gender and breed appreciated). Their eggs were different colors so they could be different breeds.
The multicolored one and the big black one with a wide large comb I think are both Roos. White one and rusty one I think are pullets (no comb or wattles to speak of still). The gray one and brown one are confounding me the most. There are 2 more black ones, but I don’t think they’re pictured well.
They are 6 weeks old.
Any thoughts?
Help please!

Could you do individual pictures of each? The last pic you posted is a cockerel, as is the "blue" one in the 2nd picture, and one in the front of the first picture (which is the same bird as the last picture, I believe). The rest are hard to see

I'm not sure about the breeds.

2,4 and 5 picture are definite cockerels, and would be a lot easier if you could post the chicks in the first pic separate.
