Small choice

I havent played the main game yet. I had downloaded it, and was really excited about all of the 8 guys and especially a certain 2, until there was one guy I wanted to play with. But after I went through the VERY LONG prologue, I found that you could only choose 4 of the guys. How long will it take to get the others, and when is ran coming?
