how to import morethan one fon with CSS

i'm re-building my profile and, as you can see, there are some parts of it that look strange bc the fonts don't work. i imported 3 fonts from CDNfonts: the one that IS visible (that looks sqaure-ish), a pixelated one that whas meant for long paragraphs and small bits of text, and another one for my display name. idk if tgis is possible to do but i don't see why not since the fonts DID work when i coded and tested everything (i used the HTML group's layout generator).
