Different fonts for navigation, body, heading

[Haan]

Hi,

I have tried several codes, but nothing seems to work. Hopefully someone can help:

I really would like to change the fonts for desktop/mobile:

Navigation/Header:                     Spinnaker
Body text/H2/H3/H4/H5/H6:     Lato Light Regular
H1/product title:                          GaramondPremrPro
