Answer 1

it is not clear why you want to save the child item into the same table as the parent items.
please review your code,
$modelAddress->id = $model->id;
you cannot assign the same id to both parent and child if you are saving it in the same table with unique constrain on the id attribute
alternative, u may create a new column [refference_id] to refer to parent id
$modelAddress->refference_id = $model->id;
