As to what's under Kakashi's mask: When Kakashi "died", he talked with his father, who wasn't wearing a mask... so take off about 20 years and you know what Kakashi looks like.

And as for Tobi... He is Madara Uchiha... but he's using Obito's body as a vessal so he can live forever or something like that....

I only say that Tobi is "Obito" because I saw that he only has 1 sharingan, and is 100% Uchiha... THAT, and his face is pretty messed up on the right side... LOOKS LIKE IT WAS CRUSHED.....
