Can i set own Fonts ? How to add them to code ?

$font_arr['fontlink'] = "<link href='http://fonts.googleapis.com/css?family=Tangerine:700&subset=latin,cyrillic,greek' rel='stylesheet' type='text/css'>";
$font_arr['fontfamily'] = "font-family: 'adventure_5.woff', Arial, serif !important; font-weight: 700;";
