[Ontario, Canada] Please Help ID my saplings!

Edit: I have dug around and found out the first specimen is an Amur Maple. Jury is still out on the second plant.

A couple weeks back, I collected a few Maple saplings which I thought to be Norway Maple (I think I was wrong.)

Fast forward to now, and I've got 3 survivors after some fungus issues and potting. One is a Manitoba Maple (Box Elder) for sure. Can anyone ID these other two, in terms of variety? I'll hold off on stating my guesses to see what you guys think.

I know it can be hard to tell when they're this young. The pictures are of them together, and then with a white background for clarity.
