I think everyone has pretty well agreed that they are that they are likely all male and that you will be able to tell for certain in a few weeks when they’re fully feathered. If you are still uncertain then make another post. And yes they need to be out in a coop and run now they are more than old enough.
You've been told over and over that they are likely all cockerels.
Whether they have testicles or ovaries, they need to be outside. Or at the very least in a large, open, well ventilated area. Living in their own filth will kill them. Pine shavings, hay, straw, wood chips, even shredded paper would be helpful too. Something other than skating around in their own feces.
No matter what your reason for raising them is, you will get better results if you give them proper housing with enough room to get away from each other. Keeping them housed in too small an area leads to stress and injuries, which in turn leads to disease, losses, and reduced production. You should try for 10 square feet per chicken outside during the day, and 5 square feet in their coop. You can get away with a bit less in the coop, but you have to employ multiple levels/poop shelves and roosts. The key is to ensure that they can get away from each other if they need to and have a comfortable, dry and draft free place to sleep.
