I tried to make "to talk with friends" based on 彼と話がしたい, so my try is this: 友達と話がする, but not only I'm not sure about this, but I also have some questions regarding its structure.
1.-Why that と? I studied that と means "and" and it can be used to make conditionals, so why is it necessary in the sentence 彼と話がしたい?
2.-Even if my attempt is correct, I have the feeling that it doesn't mean exactly what I want to express. Why using 話がする instead of using the verb 話す?
Thank you very much!
