It's unclear.

Pinkie Pie had a kid with Cheese Sandwich. Rainbow Dash and Applejack are implied to be a couple. Fluttershy appears to have hooked up with Discord. We can reasonably say these ones are all in a relationship if not properly wedded.

Twilight Sparkle seems to be single in that sense. She has a kingdom to rule and a lifetime of moving the heavens ahead of her. If the Two Sisters never got hitched, then I don't think Twilight will either.

Rarity is an utter mystery. It looks like she is married to her work, so to speak, but there is no telling whether or not she has a special somepony in her life. If so, the identity of that pony is unknown.
