Hello,
Thank you very much for choosing our theme and contacting our support.
All the theme fonts are configured in Theme Settings > Typography.
One more way is custom CSS.
You say you use WP Bakey Page Builder, you can use Custom Heading Element allowing you to chose the heading type, color, size and custom font. You can apply it not only to heading but also display your text choosing tag p
If you have any questions feel free to contact.
Best Regards
