Since the founders are a group mind they probably don't have any individual names. Except of course for the ones created in the experiment that created Odo. None of the founders seem to want to stay seperate from the group mind long enough to truely develop much individual personalities so all of them are "founder" in that sense. I did miss a lot of the later episodes so maybe I missed something but I am pretty sure that founder is the name others use for the group mind.
