Here's my take.
1. Skin tones look off. It looks too orange/pink-ish. Otherwise I think it's a good photo.
2. Same thing with skin tones. Otherwise, love her expression. Like the leading lines with the brick wall as well.
3. Sking tones look better on this one. I generally like the back drop. There are couple of things that bother me though. It's crooked, the hot spot on the upper right where presumably your OCF was located, and what they are standing on.
4. Not too crazy about this one. They look detached. I assume they were holding hands but that's not in the frame. He's got that fish look going with the smooching. Also, the skin tones look off or maybe it's just the lighting making the facial feature look flat on him? Not sure. Something's off though.
5. I like the lighting on this one. I would try to clone out the right side of his shirt. I know it's supposed to be rim lighting but it kind of sticks out like a sore thumb. Also, they were holding eachother but the hands/arms are almost entirely out of the frame.
6. Same general comments. Skin tone looks off. Hands/arms are cut off. I'd crop out the arms entirely.
7. Nice backdrop wth the "SD". Lighting looks a little on the hot side, particularly on his shirt, but otherwise it looks pleasant. Maybe clone out the orange cone on the right side of the frame?
8. Would have been better if you shot them straight on sideways instead of them angled that way, but overall I like the shot. Maybe straighten it out a little bit?
