Show profile data in public frontend

Hello, I’m a begginer using WordPress.
I use your plugin to build my own user registration form. In my form there are some checkboxes and I’d like to show that data for the general public. I know how to show the first name and other fields using the function get_users() but I’d appreciate if you tell me how to get the fields that were created with your form.
Tank you
