It's worth noting that, historically, only the unicorns have had a monarchy. The earth ponies seem to have had something resembling a representative democracy and the pegasi apparently were a militaristic, heirachial society.

I recently read a fan-fiction where Spitfire is revealed to be the current holder of the title of "Commander of the Pegasi" and one of Celestia's earth pony advisers is the current Chancellor. The scene had Celestia telling them, and Blueblood, who is Prince of the Unicorns, that she had altered the constitution that, should she or Luna (or even both) go crazy and have to be banished or killed, she's decreed that the diarchy be dismantled and Equestria go back to the old unicorn/pegasus/earth pony ruling triumverate.

Fanon aside, I suspect that there are still holders of the titles of king of the unicorns, chancellor of the earth ponies and commander of the pegasi but that the titles are now ceremonial and almost powerless. Whether they would be in the line of succession in the event that something happen to all the princesses is anyone's guess.
