i heared that Marucia's name will be "Maruxia". So that makes it all the (known) members of the Organization Maruxia, Larxene, Axel, Zexion, Lexeus and Vexen. As you can see, all the uncomfirmed names have "X" in them, but they might not be the official names, so i might be wrong. thanks to kingdomhearts2.net for the info.
