The first one, I can't really tell anything.
The second one, I know it's a shire cross, but it has a HUGE head. Sharp angle from head to neck that is not desired, and his neck seems too short, though it does have a bit of the graceful curve.
By far, the last one has the best confirmation I can see. Her head and neck meet at a nice angle, and she has a beautiful curvy neck. She is also the oldest, the others may grow into some of their oddness, but she looks the best.
Okay, now that that is over with, they are all pretty horses! I wish you luck =]
