1. Katniss: I think she needed to be the first one because she's obviously the bravest/strongest character.  She takes over raising her sister and then gives up her life for her. 

2. Rose Hathaway: She's amazing in battle and gets all the guys attention.  She doesn't care what anyone thinks of her and always goes for what she believes in.  She is basically just awesome.

3.  Tris:  Even though she's scared at first she goes against her family and joins the scariest faction. She jumps off tall ass buildings and does awesome in a fearscape. 

4. Sophie: Anyone with that much snark deserves a spot on this list.  She battles a little with magic too.  

5. Allie: She goes on such an epic journey and survives everything that is thrown at her...including becoming a vampire.
