I got rid of my two roosters (hatched) at about 17 weeks. They were starting to challenge one another and me and I did not want my kids to get in the middle or it or become challenged. I sold mine on craigslist.
I agree with all your guesses. You have some roos there. Every time you circled something, it is a roo. Sorry! I have 21 week old light brahmas and they show no where near the development as your birds do.
