Yes, you can use 'console" and "comfort" in the same sentence. #1 is just fine.
2, 3, and 4 are fine, so far as sentence structure and vocabulary are concerned. You need to differentiate the two speakers, though, with quotation marks and attribution.
5, the same to differentiate the speakers, and note that "game" is singular. Are you playing A basketball game or games? We would say "a basketball game" or "basketball games". The word game is not necessary, though (it is correct!). "Basketball" is a noun and it is known to be a game, so we would probably say, "You can play basketball with your friends." It's more indefinite; it could be one game or a whole season.
