Tree ID

We need help identifying our trees! Anyone out there who can tell what these are by their leaves? They're supposedly all flowering trees, which should help narrow the options down a bit. We need to transplant them this year, but we've misplaced the paper that came with them describing how they'll look when full grown!

The heart shaped leaves we think are from a Redbud, but the rest we don't currently have any ideas. The last one looks the cutest and is the only one with flowers this spring, which might help identify it.
