Answer 1

This will get the address for you
$obj->query->emails[0]->address;
if you want to iterate and get other addresses
foreach ( $obj->query->emails as $email ) {
echo $email->address;
}

Answer 2

You can get address & name via follow code.
// Getting email
echo $data->query->emails[0]->address;
// Getting name
echo $data->possible_persons[0]->names[0]->display;

$data = '{
