It is possible, but you will have to use several forms.
Google forms are static and cannot be changed or modified using a script during a session (the user opens the form before submitting it). You cannot pull out the values ββthat the user entered into the form before they submitted it.
As a result, you can have an initial form that collects all the values ββthat affect subsequent forms, and then use a script to get the results and create a new form (for example, with 12 fields for 12 secured users in your original example), and then send the link on this form to your end user.
