Hi Delilah!
Currently our WordPress themes only come preconfigured with fonts that are included in the Google Fonts library, and if you want to add custom fonts to your website from a different source then your best bet is to try using a plugin from the WordPress repository.
One plugin that we typically recommend for adding your own custom fonts is Use Any Font. That plugin should allow you to add any of the fonts downloaded from ezzeefonts.com to your WordPress website.
Please let us know if you have any other questions for us!
