Fruit Trees?

Ok, I need some help. We have these trees out in front of the lodge. While some are obviously just shade trees (usually cottonwood) some are fruit trees and some I THINK are fruit trees. Can you all look at the pictures here & see if you can tell what kind of tree / bush each one is? I included a close up of two of them that still had fruit. I'm pretty sure the one (the one w/ the poor closeup) is a Cherry tree. The other close up is of a bush-type... but I'm not sure. Could it be a Current? It has lots of long thorns which confuses me. Maybe it's not an edible fruit bush at all. And, the big one we think is an Apple tree. Unfortunately, there is ZERO old fruit on the ground under any of them (thanks, I suppose, to the resident elk & deer population). Anyway, if you can identify any of these, please let me know. Thanks!!
