Could you recommend some books on how to name novels?

It's an urban fantasy theme... Uh... The style of writing was relaxed, cold and humorous, with some sarcasm towards the world. The emotional scenes were more ambiguous, clear water. The main thing is to name the four main characters, two men and two women. Please help me name them according to the information of the main characters below. I don't reject the double surname. The main thing is to have a unique and novel name that people can remember at a glance. 1. XXX, male, 24 years old, Aries, height 185cm, personality: Fickle heart big radish + super narcissist + gossip man + violent man, advocating the principle of using violence to subdue violence, likes to pretend to be a pig to eat tigers, likes to look at beautiful women but loves food more. He didn't like to work and thought that eating, drinking, and having fun were the most important things in life. 2.
