Fool me twice

Not me like a crazy lady following them around for individual pictures

Welcome to the club! I'm pretty confident the white, grey, and black are pullets.

I looked back through your other posts and it appears I've responded before. Chick sexing is not an exact science... however, you may want consider looking into a sex link or auto sexing breed. This will mean you'll know just by looking at them at hatching if they're male or female. Would save you a lot of heartache!

I'm happy if they're roo's too. We have a big enough coop, run, and yard. But I appreciate everyone's replies!

Got them Feb 28...4 months-ish

Those being four months old are all pullets, including the red one. If they were roosters, their combs would be a lot bigger, their saddle would be fully in, their hackles a lot shinier, and their tails would be bigger, shinier, and curled. They would also be crowing.
I have 13 pullets that are about the same age and they're all obviously pullets. A couple of them, my Rhode Island Red and a Cinnamon Queen, has a bigger comb than your red, and they're both still pullets. Within the next month to the next few weeks you can start checking to see if they're getting ready to lay by feeling if their pelvis has started to separate. (I do this with many of my young hens to get an estimate of when they'll start laying.)

Edit: This is one of my RIR pullets at three months old, and her comb has grown since hand. She's a pullet, no doubt about it:
