There is a possibility to load custom fonts to JotForm but you need to be familiar with using custom CSS. If you want to load custom CSS you can go to Setup & Embed -> Preferences -> Form Styles then add the CSS in the Inject Custom CSS field to have some custom font.
On this link you can read more about CSS rules for custom fonts.
Also you can use Google Web Fonts inside of JotForm. You can read more about how to use Google Web fonts on this link.
In addition to what @bkljaic has mentioned above, you can also use the Form Designer to use custom fonts for your form.
Just look for the Font Options tab and select the font you want to use.
