Working on a small project on my site and im wondering how i can add more box places.

I want to add 4 more box places. Just like Middle left and Middle right but Top left, Top right and Bottom left and Bottom right.

And also while im adding more box places add one that goes above main content that are right under the menu.
Just like Simple theme have (http://general.demoflynax.com/?templ...l_simple_green)
