What is the problem you're facing? What browser is it not showing up on? Are the files you've integrated actually present on the relative paths on your webserver?
I see that you're using a shortcode for 'font' which is not read by some older web browsers.
Also, if you're going to use the same font for all areas in your document, you need not define it for each selector in CSS. You can simply define it for 'body' font and just change font-sizes for different selectors within it.
