You can pick anybody and list as many as you like. Fewer characters with good stories behind them explaining your identification with them are preferable, but whatever comes naturally to you is good. Personally, I tend to like Ted Danson's character from the TV show "Becker". He's awesome. Sometimes when I watch the show I wonder whether the writers intended that character to be a republican or democrat because he shows strong tendancies towards both, but as soon as I think I have him figured out, he surprises me somehow. It's great. Plus he's pretty much me at this stage of life, except with the excessive often untargeted negativity.
