Google font issue

I am using following google fonts
Rock Salt
Alegreya Sans
Alegreya
Fredericka the Great
Cherry Cream Soda

using this code in Custome Stylinh>Quick CSS
e.g.
@import url(http://fonts.googleapis.com/css?family=Rock+Salt);

But fonts are not showing properly on all screen.

Now I have generated font faces through fontsquirrel but Fredericka the Great font is not coming properly on chrome.
