That's a nice selection you got there! I'm certain the fruit trees will serve you well. All 3 kinds (apple, peach and plums) are quite robust and should be able to provide a nice harvest a few years down the road. But keep in mind to cut them a bit every year so the "strngth" gets into the fruits and to keep harvesting reasonable. I'm certain there will be somebody around who can show you how to do that properly in case you don't know yet.
