Roxas had a heart because Sora wasn't still a heartless, right? Roxas wanted to be reunited with Sora because many of the other members could never have the chance. Axel also displays more emotion than a lot of other members. I believe that Nomura confirmed that Axel's Heartless was defeated. I think that his emotions were returned to the Nobody. Now that Roxas and Axel pretty much... STAND OUT... they become friends. ATW/DiZ said that "His heart is returning", I think he says this because Roxas' heart was temporarily gone because Sora was in his deep sleep.
Quote from ATW: "His heart is returning. Doubtless he'll awaken very soon"
As for the 14th member. I think that she might be Aqua's Nobody... and she encourages Roxas to leave the Org. to find Sora
