I got a phone call from an old friend, he said he's already been into my city already.

I met him about two years ago , then he went to Russian, I don't know what he will talk to me?and he hasn't talked to me since then so I am excited to hear how he has been.

I cannot seem to understand the last part of that sentence, If you could explain it I may be able to help more. :)

Maybe exciting experience in Russia or the current Russian-Ukraine battle or something else.

I got a phone call from an old friend, h. He said he's already been in my city already.

The "already" at the end doesn't need to be there since you used it at the beginning. "Been" is past tense, so it shouldn't be used here if you want to say that he is currently in your city.

I met him about two years ago , t. Then he went to Russian,. I don't know what he will talk to me about?

Maybe about his exciting experience(s) in Russia or about the current Russiano-Ukraine battle orian War or about something else.
