The 2 “blonde” ones are most likely Buff Orpingtons. You have definitely have 1 female of them possible 2. The 1 looks like it could be a rooster but when I look at the tail feathers it looks like the other one. The red one is definitely a rooster. How I can tell is on the top of their heads if the comb is bigger then the other it most like a rooster and you can tell by tail feathers sometimes too. Everyone has different ways of telling male and female tho.
