today my friend called me and said he had a fight with a guy and he also told that tomorrow he is going to home and he is going to US by next month.
So a few things:
Capitalization and punctuation are pretty important in written English. Please try to practice these diligently.
Your example is what we call a "run-on" sentence. This is a sentence that should include commas and/or periods, but instead just "runs on and on".
"Tell" and "say" are different. Tell is a transitive verb that requires a direct object. I have to tell someone (even if I just tell myself). "Say" is intransitive, meaning I don't need a direct object. I say something but not to anyone.
Otherwise I'm not sure what you are asking about the "passive voice" since none of your verbs is in the passive form. If you'd like to know how to make the entire sentence passive ... well, that's a challenge since we don't usually make every verb in a sentence passive.
But I can give it a shot. Let's start by fixing the three things I pointed out, and cleaning up some of your word choices:
Today, my friend called me and said he had a fight with a guy. He also told me that tomorrow he is going home, but he's coming back to the US by next month.
Passive voice (as best I can):
Today I was called by my friend, who said he got into a fight with a guy. I was also told that he is going home, but he's coming back to the US by next month.
Notice I just changed the two verbs where I am the direct object. The rest I left alone.
