Hello @anne,
The theme itself does not have the option change the font of the menu but you can change the font using the CSS given below:
For this go to Admin Panel > Appearance > Customize > Additional CSS.
.main-navigation ul {
font-family: roboto;
}
Change the font as per your requirement.
Now as for the footer, the option edit the footer is only available in the pro version of the theme. Not only this pro version comes with lots of other exciting feature and to know about it please refer to below given link:

Best Regards!!
