Shouldn't be a problem. If they're older True Type fonts (TT) make sure you download the proper version ( pc or Mac ). Download them to you desktop then click and drag the font file into your fonts folder. Some files come with a README file and a pickpage...just load the font. Be aware that there is sometimes a difference between free fonts and those found on real font sites like Letterheadfonts.com. When you try to manipulate the fonts in your program they may not always react the way you want them to...they're just not as refined as the higher quality ones you buy. But overall, I have a lot of each on my computer and have good results.
