What do I have roosters or hens

So I joined last night and thought I'd get some better photos this morning.

I think they are all pullets. None strike me as cockerels.

Sometimes you can't tell while they're young unless they start courting females, fighting, trying to crow, or generally just acting like a cock I'm with GloryFarm though, none really look like roosters.

Well another question can hens fight. The two Plymouths fight with each other and the 3 smaller Sussex fight between themselves. Also this is my other chook which Is supposed to be a hen but I've been told is a rooster.

2 and 6 are your only females. 4 is a Black Sexlink, not a Rock. 2 and 3 aren't Sussex either, they are crosses of some kind. Last one "red" is a male as well.

Yeah that looks like it could be a rooster, how old is it? If it's still young give it some months and it'll be obvious.

Yes females can fight some to establish and uphold pecking orders. If it's a new flock or has new members they may pick on each other for a while. Roosters tend to be more rough with each other and can actually engage in short flogging fights and chase each other around the yard, where as females tend to run up to each other and try to bob their heads higher than each other or chase each other shortly. That doesn't mean hens can't get nasty though. One time we did have a chicken who--overnight--had her scalp pecked clean by the others. She was still alive but her skull and bone was all that was on top of her head. She was our favorite chicken but was also at the bottom of the pecking order. We did what we could to nurse her back to health but she either died or my dad put her down, I don't remember.

Where did you get these birds from as some don't strike me as pure breeds. How old are the two barred birds?
I would agree with Gray Farms also. 2 and 6 are looking like the only pullets. 1 and 3 have far too much pink/red comb and wattle development to be anything other than cockerels at such a young age.
No.5 has male coloured (lighter) barring due to two copies of the barring gene. I think I can also make out pointed hackle feathers. Depending on the age of No.4 that comb and wattle development is very red and even though it has the darker barring of a barred rock pullet with a single copy of the barring gene, my gut feeling is that it is a mixed breed cockerel with just a single barring gene, so as suggested it may be a black sex link cockerel. At 21 weeks No 6 is looking like a pullet and the red bird is definitely, without a shadow of a doubt, a cockerel.
You are going to need to figure out what you are going to do with all of those boys because it is going to get awfully noisy soon and they are going to make those two girls lives a misery once their hormones kick in.

Thanks everyone no 6 and brown roo came from a private seller who is more then happy to swap the roo. The others are from local farm supply shop. I have a buyer chasing the rocks so now I know for sure I'm going to ship them off. Then I will be down to 2 Roos.
