class allLeave extends Model
{
    public function empolyees()

Answer 1

This can be done ( Based on code you have shared ). You should be doing something like

$allLeave = App\allLeave::find(1);

# one-to-many, employees is a collection. ["emp_01_full_name", ....]
$data = $allLeave->employees->pluck('full_name')->values();

Update

/* Your view will have an array like
 $data = [
    ['leave_type' => 'casual', 'leave_days' => 2, 'full_name' => 'farooq']
    ...
 ]
*/
$data = $allLeave->pluck(['leave_type', 'leave_days', 'employees.full_name'])->values();

How to use it in your view

return view('leave/allLeave', compact(['data']));

OR

return view('leave/allLeave', ['data' => $data]);
