For 24hrs I have been really struggling to find how to access the email and address fields. I think I've tried every combination there is

my last attempt

$obj = json_decode($json);
$emails = $obj->emails->address;

$data = json_decode($data);
// Getting email
echo $data->query->emails[0]->address;

// Getting name
echo $data->possible_persons[0]->names[0]->display;

Answer 2

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;
}
