Need help identifying breed of these chicks please

[Mandi85]

My grandma just got these chicks today and she did not ask and was not given breed info. Can anyone tell me what they might be? The black and yellow one (top left) has feathers on its feet.

Top left. Cochin, right top---barred rock or black sex-link male, bottom left--possible RIR or red sex-link, bottom right yellow buff. Is my guesses.
