Most of that is due to your theme. 4 of the JS files are not from Q2A, and 5 of the CSS files are not either.
You should combine the last 4 JS into one file.
Not sure why there are 3 font CSS files, usually having that many fonts on a page is a bad idea. Also the 2 Google font ones can be combined into one file if you select them both via the Google font website.
You should be able to combine the other CSS files into one.
