Yup. That's all of them. She played a Q on Voyager, first appeared as a Vulcan Star Fleet Medic on TNG and followed that with her semi-regular appearance as the mother of Worf's child Alexander. Combs, IIANM, first appeared on DS9 (then back on DS9 in a second role), showed up on Voyager in one episode (third role) and has now been on four Enterprise eps, three times as Shran. So Combs gets the nod for five roles, both Combs and Plakson each have been in three series (though not completely the same), and Plakson gets braggin rights for having been first on board.
