In general, different species don't pollinate each other. Apricots and Asian or American plums could pollinate each other if they bloomed at the same time, but apricots generally bloom earlier than plums, so they usually don't get an opportunity to pollinate each other.
Plums are complicated, since there are several different Asian and American species that generally can all pollinate each other. There are also a lot of hybrid cultivars for cold climates that are crosses between Asian and American species. However, these hybrids generally can't pollinate anything else. It's recommended that you have a pure American plum to pollinate them.
Here's a very interesting article from the University of Saskatchewan on the pollination of cold-hardy plums:
Sour cherries are generally self-pollinating. I think sweet cherries don't pollinate anything else.
