1/ Are all features of different demos switcheable ? Could I chose the demo Organic homepage and insert the footer of demo homepage fashion #2 with the menu layout #3, for instance ?
=> All demos layout just different from order section, header, footer config so you can create demo by yourself by change the setting. That mean you can choose Organic with Footer from fashion 2 and menu from layout #3.
2/ Where can I see the fonts available for this theme ? (particularly for the menu and sub-menus).
=> You can change font for body and heading from Theme Setting > Typography
If you want to change font for menu, you can add your custom CSS or use this free app: https://apps.shopify.com/fontify-change-customize-font-for-your-store
