1: Usopp (he's the toughest "regular human." and his "betrayal" of Luffy was dramatic, yet brave because he knew who he was going up against. he actually stands in the face of fear, sometimes. Most of the time, he runs away. But, every once in a while, especially when his Nakama are insulted, he takes the plate [the merrychristmas/mr.4 fight come into mind)
2: Luffy (out of all the characters, his personality is a medley. Usually, he acts dumb, but every once in a while he'll surprise everyone with an immense amount of claritiy. During the arabasta arc, he has one of tese moments with Vivi.)
3: Mr.2/ Bon Clay (Funny as hell. He challenged Hina-- Twice. and lost-- Twice. he's got guts.)
4. Enel (eneru?) because the power to control electricity would be damn cool.
5: Sanji (I want to be able to kick like that. or cook...)
6: Zoro: swords are awesome, and training to take someone like Mihawk down...)
7: Shanks So mysterious. I like that in characters.
8: Jango: He was a funny villain. You gotta admit that.
9: Kuro. My all time favorite villain (Jango technically doesn't count as one.)
10: Franky: weird Mofo. turning his entire body into something from nothing but scraps... Butthen he goes around and wears a speedo everywhere.
well, that is my list... I can name a few more if you want, but I don't think it'll be necessary.
