You can add other classes to individual menu items manually.
Within the Appearance->Menus page, click Screen Options in the top right corner.
You will see a menu that looks like this:
Check off CSS Classes and it will give you an extra form field per page item. Adding a custom class will allow you to target each specific list element with CSS of JavaScript on the front-end.
You can change the names of your menu items manually as well. They do not have to mirror the actual page names.
