Welcome to Kingdom Hearts Answers. What would you like to know?

This question has already been asked, however I'll answer anyways. Just to clarify though, there is no difference between the seven guardians of light and the seven protectors of light, they're the same thing. As for who they are, it is confirmed, by Mickey, in Dream Drop Distance, that Aqua, Ventus, and Terra were three of them. Mickey confirmed himself as one of them. It's obvious that Riku and Sora are two of them. And the secret ending of Dream Drop Distance has Yen Sid talking about bringing in someone else to fill the spot of the seventh guardian of light, that person is Kairi and is currently being trained to properly wield a Keyblade. Lea is not one of them, nor is Yen Sid.  Timelinesplitter Chaos 02:53, October 9, 2012 (UTC)
