Assigning User to a Custom defined Role

I can create a custom defined Role easily within the Console. I haven’t found a way to add users to this custom Role.

Please see here:

That is exactly what I was looking for thanks!

I following the procedure of adding a user to a Role from the document you pointed me to and now the added user(s) are part of the AuthenticatedUser Role and the custom Role. Can I remove the user from the AuthenticatedUser Role?

No, that would not make sense. A “user” becomes a legitimate user only after they login and authenticate themselves - meaning the app will know the user is who he says he is. At that point the user will automatically be a part of AuthenticatedUser role. Someone who is not part of that role is just a guest and therefore belongs to the NotAuthenticatedUser role.
