Hi...
The demo 9 is not actually completed, its still under development.
In the demo we have only added slider right now, other styling and layouts are still to be changed. That's why its not present in the demo switcher as of now.

You can change the fonts from the customize->body->select font family. Make sure first you have selected the fonts in the wplms-> fonts manager (

Similarly you can select fonts in body, header etc.
