You will have to either use FTP to modify the files or the built-in storefront editor. Or if you want to have admin control you will have to build a module to allow you to change these from admin.

These are hardcoded in twig files. All XC Template Monster themes home page features are hardcoded in the template files and there is no control over these at all.
