Female anatomy 7 (cartoonish)

It's part of the commission I'm doing. But I have 2 reasons for uploading it: 
2.  I noticed that  people like to compare characters what means that they look/observe carefully characters they talk about. So I was wondering if you'd guess who those girls above are. If you do then.. Then I'll think whats next  

EDIT:

ANSWERS ARE HERE:
 

 
 1. To show differences in bodytypes. I was often a listener in many lively discussions about anatomy and proportions. Those are  to show how different proportions can be used for different characters and different styles. So. Before we talk about anatomy we should  think if we talk about bodytype/style or correct (in our mind) proportions  because those are very often mistaken.
