It's evident from the trailers that the members of the Guardians Of The Galaxy have gone through some changes since the first movie has come out. During a Guardians Of The Galaxy Vol. 2 set visit, Chris Pratt was asked about Star-Lord's growth in the time between the movies. How has the character evolved? He explained, "He definitely feels a responsibility, feels like he?s a leader, but it?s still a group of misfits. He still has to deal with Rocket, and he still has to deal with Drax and Gamora, and the way that it is. There?s still a lot of fun to be had there. He certainly doesn?t have a mastery on how to be a leader of this group. But I think he feels like the leader of this group at the beginning of this."
