The Home page default template is the home.php located in your custom theme directory. If it doesn’t exists, just create that file with the proper name “home.php”. Otherwise, you can create a custom template with whatever name (except those reserved by the WordPress hierarchy, but you need to make that file a template), create a page in the WordPress admin which will use that template and then configure WordPress to display that static page as the home page.

But you want your home page to display the users list showed with their related ACF custom fields, that’s it?
