8 week and 15 week Pullet or cockerel?

[AllMyEggsiesLiveInTexas]

So I ordered 6 female chicks from my pet chicken but we all know how that goes. At least one will turn out to be a rooster. So here are my pics of the 8 week old chicks. The one I am 90% positive is a roo is the BCM. Let me know your thoughts or opinions.
I also have 3 older chickens (15 weeks) I hope are all hens. We shall see. Feel free to leave thoughts and opinions on those too. Thanks in advance from this first time chicken owner. I love my birds! So rewarding, entertaining and fun to raise.

#1 BCM cockerel?
#2 Crested Cream Legbar Pullet
#3 Mottled Houdan Pullet
#4 White crested polish pullet
#5 wellsummer pullet
#6 olive egger Pullet?
#7 Easter egger Pullet?
#8 Barred Rock Pullet
#9 Blue Andalusian Pullet

I think you're right on gender and breed. They don't need a heat lamp anymore if that's what that red light is.

Thanks!
They were only 6 weeks old when I first put them outside. They were separated from the older chickens and couldn’t be in the coop at that point. So the heat lamp is only set to come on if temps drop below 65 with Inkbird. I’m going to have to keep them separated until they get on the same feed because the big girls will change to layer feed next week.

From the breeds I know, you're lucky to have pullets.

Aww you have a little cross beak! Please don't despair I have a 2 year old Silkie hen who is my favorite she is the sweetest she also has a cross beak too she gets along just fine you will just need to watch it and trim it or have it trimmed a few times per year as they don't wear them down like a chicken with a normal beak but they get along quite well! I have had Elvis beak trimmed several times and she doesn't seem to care as soon as its trimmed she's on her way back to scratching and eating! I have it done because I am a scardy about it LOL but the vets are normally happy to show you how to do it! Beautiful flock!
