I want to know some names in western novels

I'm writing a western fantasy novel now, but it's hard to think of names. For example, what should I call the schemer? What should I call the assassin? What should I call the bad guy? What should I call the kind guy? Please help me suggest some names. It's best if you can help me make a list like this [Elf Race: XX XX] The protagonist's opponent (the kind that's a little bad): XXX XXX XXX One or two wasn't enough. He needed a large number. He wanted a name that would let people see his character at a glance.
