Have you read Help:How to import Google Fonts?

In order to use different fonts for different languages, you need to identify the different languages. For instance: This sentence is in English. この文は日本語です. Then, your CSS would look something like this: " " would be your font fallback sequence (i.e. what the browser should use if the first font doesn't work for whatever reason).

If I may, there are some things I noticed about your current CSS I would like to mention. First, your import of the ModernRail CSS will not work. It needs to be at the top of Common.css like the other imports. Second, you are missing "MediaWiki:" and have an extra ".css" when importing the RectangularButtons CSS. Third, you can combine all of your CSS imports into a single import. The above CSS already includes the ModernRail CSS and change to RectangularButtons CSS. You don't have to do it this way but leaving them separate negates the primary benefit of using load.php instead of direct URLs.
