Hi @wonderacademie,
1.) No, actually the headline font on your footer is "Amatic SC"
and the copy text font is "Book Antiqua"
which is the same on the body (only smaller). Body Font and Headings Font can be setup under Theme Options > Typography
Body Font
Headings Font
2.) Regretfully, like the background-color there is no option to change that background-color on the footer menu but with custom CSS.
You can find the proper CSS code selector using the Chrome browser Developer Toolbar
For the CSS code itself, I suggest that you get started with this tutorial
3.) No, you can’t. However, you can do it on the Global Block, in the global block, you can design a section like on the page and bring that anywhere on the page using its shortcode. When you’re working on the Global Block look for the element called Social. Now that I mention this, I think you should do the second column as a Global Block as well.
4.) That will automatically adjust, if you disable the Footer Social icons on the bottom footer it will automatically adjust. Adjusting it manually will require a custom CSS.
Thanks,
