Li Shang, Chien Po, Yao, and Ling (Disney's Mulan) as Jon Snow, Samwell Tarly, Grenn, and Pyp (Game of Thrones)
Li Shang as Jon Snow felt perfect. They said that Jon looked a lot like his father. Both are great leaders and fighters of noble birth.
As for the others, you have the fat gentle one, one stocky tough one, and the stringbean funny one.
