Display values of a list table in eloquent using laravel 5

I have this table with 4 id's related to other tables.

Table List:

  id   table1_id    table2_id table3_id   table4_id
  1    2             3        2           1
  2    1             4        3           3

I want now to output the values related to that table's ids

  id   table1_name    table2_name  table3_name    table4_name
  1    jay            student       singer        actor
  2    jeane           teacher      drummer       actress

ListController:

     public function index()
{   
   $res = ListModel::with('table1','table2','table3','table4')->get();

    $foreach($res as r){

       return $r->table1_name;
    }

   return view('list.index',compact('res'));
}

My problem here is that the output will be null instead of jay.How can I display now the values?Please help..

{
    Schema::create('list_table', function (Blueprint $table) {
        $table->increments('id');

        $table->string('table2_id');
        $table->string('table3_id');
        $table->string('table4_id');
        $table->timestamps();
