"So what do I do now?"
You should move the folders that succeded in downloading and extraction to one of your fonts directories.

Ryan L. McIntyre (a.k.a. ryanoasis) does have a few suggestions. But they need some improvements.

For instance when he mentions the "font directory" he's talking about putting the fonts into a
user-specific font directory located at ~/.local/share/fonts, which only installs the font for
one user.

System-wide fonts are either stored in /usr/share/fonts (especially if they were installed with apt)
or /usr/local/share/fonts (user installed). We want to put our new fonts in /usr/local/share/fonts.
