What breeds/genders are my chicks?

[FeatherLace]

Hi I have twelve chicks, 8 of them I know the breed of but not the gender, and 4 that I don't know the breed or gender. I have 2 Russian Orloffs and 2 Lakemvelders aged 4 weeks old that I don't know the genders of, 4 Ayam Cemanis that I don't know the gender of, and 4 mystery breed bantams that I'm PRETTY sure 3/4 are hens. I included pictures of all 4 lakens and Russians, one of my fluffy bantams, and both of my tiny black bantams. I think my fluffies are hens but I'm not sure the breed, and I think one of the tiny black ones are a rooster, but I'm not sure if the two are even the same breed due to the vastly different combs. Could you guys give me your guesses on genders for them all and breeds for the bantams? The bantams are 8 weeks old. Each pic is of a different chick. I did not include my Cemanis because I can't tell them apart lol. Anything helps, thank you!

The 4th chicken looks like it might be a rooster because it has a much larger comb than the others. The 6th might also be a roo, but I can't be too certain on that one.

The ones in the fourth and sixth pictures appear to be cockerels.

Too young for your Orloffs. Unsure on Lakenvelder with the smaller comb, but the larger combed one is a cockerel. Feather legged one if it has a single comb is likely a Gold Laced Cochin and looking pullet-y for now. The black one with a large comb is a cockerel and looks to be a Rosecomb Bantam. His counterpart is looking pullet-y and if she has a rosecomb, likely same breed

I looked up those breeds and thats almost exactly what they're looking like, except the my feather footed ones only have the head and wings like a gold laced and the body is solid black. But the rosecomb looks spot on! Hes even getting that white patch on his ears. His female counterpart has a normal comb though, no sign of rosecomb at all. How will I tell sex with the Orloffs? They only have a flat part where their comb would be?

Do I need to include better pictures?
