adding multiple content to homepage
You can easily customize your theme depend upon your requirement

Open up your theme's .info file and you should see some regions like this:

regions[featured] = Featured

regions[content] = Content

regions[sidebar_first] = Sidebar first

regions[sidebar_second] = Sidebar second

to add a new region just type in a new one in that .info file. I'd be careful of replacing any though as there are several regions in D7 that are required.

Then you'll need to print out your new region in your page.tpl.php file which goes something like this now:

&lt;?php if ($page['sidebar_first']): ?&gt;
      &lt;div id="sidebar-first" class="column sidebar"&gt;&lt;div class="section"&gt;
        &lt;?php print render($page['sidebar_first']); ?&gt;
      &lt;/div&gt;&lt;/div&gt; &lt;!-- /.section, /#sidebar-first --&gt;
    &lt;?php endif; ?&gt;


Don't forget to clear your cache or you won't see the new region. It really helps to poke around in some other D7 themes and see how they've done things also.
