Which job/career can i get by learning martial arts like bruce lee except coach? Can it give good money?

The obvious one is to become an instructor, but instead of becoming a coach for twelve year olds or something like that, you could become a trainer for film, or a fight choreographer. Additionally, you have the option of fighting competitively. If you were to get a criminal justice degree, it would be a great point to put on a resume for any field agent or even just as a cop. All of these jobs can be fairly competitive and don't necessarily pay big bucks. The more glamourous jobs that pay better are the harder ones to get into and you'd probably have to do some of the stuff you don't like (aka teaching martial arts classes or starting on a completely different path at first) before you could even consider it. Since you seem to like Bruce Lee, you might have the drive to study acting and become an action movie star just like him. If you want to be paid to do martial arts, though, you're going to have to really work hard and sometimes do stuff you don't want to do in order to get to where you want to be. There aren't many options out there, but if you're set on one, don't let anyone or anything stop you from making your dreams come true.
