A ton of JavaScript questions

Here is the main JavaScript. I have comments I was hoping someone could answer the questions for me.

    <!--JavaScript-->
    <script src="js/jquery-1.10.2.js"></script> (i know this is Jquery even though I didn't label it in rates.php.)
    <!--bootstrap core JavaScript-->
    <script src="js/bootstrap.min.js"></script>
    <!--Jquery plugin-->
    <script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.3/jquery.easing.min.js"></script>
    <!--Unsure-->
    <script src="js/classie.js"></script>
    <!--Affects the menu bar size and scrolling? Will have to alter it to retain full functionality on multiple pages?-->
    <script src="js/cbpAnimatedHeader.js"></script>
    <!--JavaScript for the freelancer template-->
    <script src="js/freelancer.js"></script>
    <!--Simple script to hide or display buttons-->
    <script src="js/rates.js"></script>

This is a small business and I'm going to use this starter template first. But I feel like I should understand the JavaScript to use it right. Apprecaite the help if they want me to I can beef it up later.

The file in question is rates.php. Thanks. Just whatever you all think I should understand I will learn what you think and any help would be appreciated.
