The funniest way that I feel capable to earn money is to becaome a clown and tryingo try to connect with people, either in the street or into a theater.

- became is past tense, you want to use to become which is infinitive (same for trying -> to try)
- into a theater is used when you're talking about moving i.e I'm going into the theater to do xyz, if you are talking about being in the theater then you just use in

I took clown classes some years ago and I loved it, I haven't found any other way as powerful as this one to connect with other personople, because the people in the public are a really important characters in a clown show.

- having 'one' is not incorrect but far more natural to leave it out then to put it in
- either put other people (plural) or another person (singular)
- add s to characters as you are talking about people which are plural

It is like a dialogue, the clown in the stage giveing an action, a word or just a glance to the public and the public answers by laughing, moving, or clapping.

- give to giving to correct tense
- adding by makes it the sentence more natural here

Clowns need to eat too!

Punctuation needed - can be a period (.) or an exclamation mark. In this case, given the funny nature of the question, it might be worth using !
