Wht exactly are these stars and titles that are below and above our names?

It's in the AGN Members' Handbook, the post above yours.

If you want to know what post amount is necessary for a given star/rank, you can look in the Current Star/Rank System Update thread in Official Announcements.

You can also check out Newbie Central (http://newbiecentral.armageddongames.com/), it should answer most of your questions, but if not, jump back here and ask away.
