Hey so I downloaded a few fonts and the FAQ part tells me that to downlaod the font I just need to click right click on it and click install. But the font I downloaded has a bunch of files. It has bold, old italic, hollow italic, hollow bold and a bunch of files with these names on it. So what do I do on this case? If I install just the regular one will the others be installed too? Or do I need to install them like different fonts?

You can only use fonts that are installed.

If you want all those fonts, then install each one. If not, only install the ones that you need.
