naming characters

[BardTard]

What I wanna do is make video games, and the hardest thing to do next to coming up with storylines is naming the characters. The storyline I have now, I really want to give the characters fitting names, like names that would describe their personality, or something. So if you wouldn't mind, I'd really appreciate it if you would tell me what you think of these characters just based on names alone:

Amy Hyde (female)
Alex Crow (male)
Davine Diamond (female)

I might be changing the names again as I see fit... unless I decide these names are alright. The only one that I'll probably change is Randi... I need that to be a unisex name that's spelled the same way male and female way but Randi is the best name...

Anything would be helpful, please tell me what you think they look like, or what they act like, talk like, anything. Thanks in advance, it would be alot of help!
