Use Matriculation as Sign Up credential, then Automatic Redirect

Hello Sir,
This is the Login Form that I want to create– https://prnt.sc/LY4FxwFIPmEJ

Nothing fancy. Just a simple Login Form that uses “Matriculation Number” and Password as the Sign Up and Login credentials.

The usual WordPress flow is that people will register with Username, Email and Password.

But in my Use Case, it is an Alumni website. So they want people to register with “Matriculation Number” and Password, as you can see here– https://prnt.sc/LY4FxwFIPmEJ

1.) Is it possible that instead of using the default flow of Username, Email, Password to Register and Login, that I can have a Field called “Matriculation Number” and my users can Register with the Matriculation Number field?

1b.) Since Matriculation Number is not the default fields of Username or Email, will Front End Users plugin store this “Matriculation Number” Metadata effectively?

1c.) As you can see from my sample Form, there is no Field Label showing on the Form. Just the Placeholders inside the Form Field.

Is that possible with this plugin?

2.) There is a Message saying “Welcome” on my Login Form. Then there is a sub message after the Welcome Text, as you see on my Form here– https://prnt.sc/LY4FxwFIPmEJ

Is there a possibility to be able to customize the Login Form and Register Pages to include these additional information?

3.) AUTOMATIC REDIRECT:
I will like to totally hide the default WP Login Page— insomuch that, even if a user deliberately types “mydomain/wp-login“, it should still land them in the Custom created Front End Users Custom Login Page.

Is this possible with this plugin?

Needing to hear from you soon.
Regards.
