For all the other characters (sans Celes), I made sure there were lore reasons for the whole talking to humans thing. Celes was initially a joke character in another RP (the only sort-of canon I can even site is that Kangaskhan Kid from that old Indigo episode, or maybe N?), so I made it more as a WTF gimmick than really anything. 

If it makes you feel better, she was so young when she was found that she adapted to understanding Dragonites since she was around them, and only them. Really though, Celes talks to Dragonites because she's Celes.

When you say Alakazam and Metagross do you mean telepathy since they're so smart?
