How can I change a page's title for each page individually? I am wondering if there is a way that I can change the page titles so that users can see a nice title but that at the same time, the internal title of that same page be different?
You can use a module that allows you to change it each time or use a different pattern than default Drupal: 

Metatag

This module allows you to control a lot more than just the Page title.
