New flock acquired, need help

[RollinStoned]

New to raising chickens and have acquired 12 chicks recently. Ages rage from 5 weeks to almost 7 weeks old. Unfortunately I'm not able to tell the gender and possibly some of the breeds. Could I get a hand in figuring out genders and the breeds I'm on sure of? How should I post the pictures of them to get the help? 12 individual pictures. For now I'll post one so yall know what im working with here and can accommodate more pictures if needed

I think both of the chickens on the ground are roos. There is one buff chicken that looks really pink for 5-7 weeks. It could go either way. Crested bantam chicken I guess is a Pullet

I see three cockerels. Two on the ground, and one on the right roost bar (the buff bird).

I'd feel better guessing the breeds from closer pictures. The red cockerel in the front look like he could possibly be a Rhode Island Red, and the (mostly) buff bird on the left roost bar looks like a lemon Pyle brahma pullet. Your buff cockerel could be a buff Orpington, but I can't see his comb clearly. Looks like you've got a couple of Olive Eggers too

I see one RIR on floor, sapphire gems, some kinda Brahma left roost, buff orp right roost front, and an Easter egger back right roost.

My guesses:
Buff with feathered feet-Buff Cochin
Buff clean legs-Buff Orpington
Two grey on right-Sapphire Gem
Red on floor-RIR male
Black on floor-Black Australorpe male
Buff with crest- Buff Polish
Grey on left-Sapphire Gem
Black on left-Black Australorpe

Thank you for the help so far yall. For sure I know 2 are RIR and 1 Pavlovskaya, 1 Icelandic, 1 bkue Americuna, 1 lemon pyle brahma, 2 Easter Eggers and 3 black copper marans. The yellow bird with naked legs im confussed about but yall mentioned Buff Orpington. So that makes 12 if yall agree with me. I'm trying to get better photos. More individuals but it's hard at the moment.
They haven't been going in the coop at night so I've been doing the leave them in the coop for a few days method. When I can let them out again I can provide better photos. Again thank yall for the help. So far I'm enjoying the forums and site.

With the better pictures what I called a Buff Cochin is actually a Brahma and some of the Sapphire Gems are EE

I have let the birds out of the coop today. And got better pictures of with the help help here we believe these to be the males out of the bunch. Do you agree? Also might be possible I'll have a couple more as the other 2 marans jave combs coming in now to but not as large as the one posted just now.

I would say those are all males.
