Module development and code questions

Is it impossible to use a Multivalued entity referenced field to be used as relationships?

For example, if I have a field with 'Allowed number of values' = 2, and I want to have a view with a relationship to each one of the field values.

Can I do that or is it not possible currently?

In the callback I assign a number to an integer numeric field, it works because it displays it. When I save the movement the number is not saved.
I did various tests but didn't understand why you don't save it
The field is field_nu_hour_mission (integer)
If I write the number from Tstiera it displays it and stores it

Hello,

I have some checkboxes instead written text comments. One group with some rules create content, second group can add comments with (status). And third group should be able change status of these comments only. I need set one field which can be modify by other users.

Example.

I will create content, friend will create 5 comments in my content with statuses "not solved". My next friend change these statuses to "solved".

Is that possible do with drupal?

I am making a form using formbuilder, and it has some ajax on it. I am having trouble trying to get values on the submit handler of the ajax field. 

I have a parent container called ['isbn'],

  $form['isbn'] = [
'#type' => 'container',
'#id' => 'isbn_search',
  ];

and inside of that are two children:

['isbn']['number'] - which is a textfield
