Amy...? XD And don't forget about Vector (though then again, you could think of the math vectors). And I doubt Charmy's named after a noun. Espio is derived from "espionage", which fits him, of course... XD
*Sonic fan here*
That's pretty cool, though :3 It is a pretty word, and I like it better than "Gail" XD
Cool~ It's been the name for one of my main characters that I created for some time, though I assume you came up with the character's name from someplace different than where I got it from XD
Being into the PokeSpecial manga, and noticing how all the main characters are named after the games, I named Gale after Gale of Darkness, my favorite of the Orre region games XD Then her brother is Colin, derived from "Colesseum". But yeah XD
