In films there are general characters that are recognised in films who help the genre of the film and story-line flow along. Below are the most popular type of characters featured and the type of role that they play, also with a few examples I have found from recent modern films.
The popular girl: The popular girl usually has friends and enemies. You either like her or you don't, or just pretend to like her to gain popularity.

Both girls in their films are at the peak of popularity, however, towards the end of the film both lose respect from some of their peers at their school.

Duke - She's the man

The Wanderer: The character which puts themselves in situations which are hard to handle and turn out to be fatal. However they manage to escape it in some way, the wanderer is often the seen as the weakest within the group.
Bella Swan - Twilight

The Final girl: The final girl is the last character left alive to confront the killer. She may sometimes turn out to be more intelligent than the other victims who have been killed and may be seen as an 'action girl' or 'hero'.
Laurie Storde - Halloween
She is the last girl to confront the killer but is also saved by one of the male characters.
The pervert: The pervert is the character who puts themselves in situations that allows them to get closer to a girl that they have put their eye on.
