I think that James was Mask's real name, and that the James we saw was a creation of The Superstar ability that probably represented Mask when he was young, who looked up to superheroes (and possibly Lucha Libres based on his appearance).

About Kenpachi, I think that it just means that he's not coming back for a while, and she may even think he might get killed in his fight. I believe that Kenpachi and Unohana may actually still be fighting at this point in time, and when they showed the fight earlier, they just went farther into the future to show the entire fight instead of just cutting it off. After all, if they weren't still fighting, it wouldn't really make sense that he hasn't come back. And hopefully he doesn't come back with Bankai. That would just ruin everything.
