Thank you for writing in, you can utilize the Fonts Manager this is like your palette of fonts, you can define fonts there as many as you need.
After you have defined your fonts, navigate to Theme Options > Typography and enable the Font Manager
Then scroll just below that and you'll find the Body Font and Headings Font option, these will be your general body text font and headline font respectively.
And then if you want a specific font on a specific text/headline, you can do that on the Font Family option of the Text/Headline itself.
Hope it helps,
