I use some fonts in my new website that do not exist by default on normal user computers.
After some search I got that there are some tools that might help, like Google web-fonts.
Fonts that I used are : Bebas , Sansation and Quicksand
But I couldn't find them on Google web fonts.
How do I do use these fonts ?
And what are other cross browser solutions?
Different fonts are created by different font foundries. Not all fonts will be found in the same place. And not all fonts are available to be used as web fonts because of font-licensing.
Fonts are not always free and good fonts are rarely free.
You can usually find out if a font is available as a web font, and who owns the font by googling the font name plus "@font-face".
You absolutely should know where you'll be getting the fonts you'll be working with in advance. If you have three fonts that come from three different font-services then that's bad. Firefox especially wont like it much and you'll have some pretty bad fout problems.
Fortunately for you, all those fonts are available through font-squirrel
Bebas http://www.fontsquirrel.com/fontfacedemo/Bebas
Sansation http://www.fontsquirrel.com/fonts/Sansation
Quicksand http://www.fontsquirrel.com/fonts/Quicksand
What you will want to do is download all those fonts, them run them through the @font-face generator

HOWEVER It reads to me like you don't really understand what @font-face is, or how it works. So I'd recommend reading up on it some more.
