Plums, Gages, Damsons, Mirabelles and Bullaces are all very closely related trees in the Group Prunus domestica.
They will all happily pollinate each other, when they are in flower at the same time.
How the plum pollination groups work:
A tree will cross-pollinate with trees in its own group and the groups next to it.

Almost all the trees in the plum family that we grow are either reliably self fertile or at least partially self fertile, so pollination is much less of an issue with plums than with most other fruit trees.
