Sitcom Characters

Well for English I must create a sitcom script and I need a detailed view of each of the characters personal, physical, hobbies, background features - really as much as possible. I need a minimum of 10 students, so it would be helpful if you guys just give me some ideas of what these students would be like.

This format would be appreciated but not necessary.
(This is the characters)

I am extremely thankful to all contributions.
