Was Easter already 11 weeks ago? Wow. At 11 weeks this should not be that hard. Talking about the 5 photos in your post #13, looking at just the combs and wattles, not of them look that bright red. At that age they should be brighter red so that is a good sign.
That first one, the red one with a white tail, is not a RIR. From the body build, posture, and heavy legs that could be a boy. The hackle feathers look a little sharp. I'm not sure on that one. I don't know any breed TSC sells that have a red body and white tail, but some red sex links are colored like that. If it is a red sex link and is red, it's a girl. I'd say probably a girl but I'm not 100% sure.
The last one, a GLW, also has the posture, build, and legs of a boy. Saddle feathers look rounded but hackle feathers could be sharp. The bird has noticeable wattles, but they are not bright red. I get mixed signals on this one, could go either way.
The other three should be girls.
