Help with sexing of 9 week old RIRs

[stichfarm]

I received 10 RIRs free from a friend and I think 8 of them are NOT pullets... input is greatly appreciated! They are almost 9 weeks old. These are the best photos I could get this morning before they decided to rush my camera You can see the 2 I am confident are pullets in the last photo. Then again, I could be very mistaken... my first time having chickens Thank you!

They look more like Production Reds. I see a lot of cockerels, could you label them to say who is who?

Every one with a big red comb is a rooster.
