You need to put font files in template's css directory (same place where template_css.css is located), that files are <font name>.eot and <font name>.ttf. Then you need to define them in css, open template_css.css and at begining(before you use them) add definition:
@font-face {
font-family: <Font name you will use>;
src: url('<font file name>.eot');
}
you can also add default properties in above definition for that font like font-weight: bold;
then use font by name you give it just like any other font.
Second solution is to use google fonts (just google).
You add reference you copy/paste from googl's page and you add it in head section of index.php of template before any other css reference. Then use it like any other font.
