Based upon the shape and color, it is likely a Japanese plum. This can be confusing, as all of the Japanese plum cultivars developed in the US have American names. Japanese plums are partially self-fertile.
It could have resulted from a cross with an American sand plum, which is more reliably self-fruitful, but less consistent. They are also less prone to disease.
The key with plums, aside from proper pruning, is to grown them in a thicket, or to graft on a different variety of the same kind of plum. Yours seem to be pollenating just fine, and are on a healthy tree, so, unless they are being pollenated by something else that you are risking moving/losing, adding more trees to form a thicket likely won't be necessary.
