Help with 9-week-old chicks breed and gender

[giantshark18]

Can you help identify the breed and gender of these 9-week-old chicks? We bought as Pullets from Tractor Supply, but I think a couple may be roos based on size.
We have another set at 6 weeks (not pictured), and we lost track of what we bought for either set as we were going to different tractor supply's to get different breeds.

Black and white looks to be a Light Brahma. Red with yellow legs is likely a Cinnamon Queen.

I agree with the Light Brahmas and Cinnamon Queen. 4&5 might be White Leghorns and 6 might be a Chocolate Orpington.

I don't see anyone standing out as obvious cockerels, to me.

I think you right on the chocolate orphington as I recall they only had one chocolate orphington left when we bought the chicks.

First 3 are light Brahmas, 4 and 5 are white Leghorns, 6 Chocolate Orp, and 7 and 8 might be some sort of Production Red. Not seeing any cockerels so far.
