Answer 1

There are two ways. Based on your code, I am not sure if you got a string of that data or already an object. If you only got data back, it is a string and you first have to convert the JSON into PHP array or object.
1 - You could convert the JSON to an array:
$msg = json_decode($msg,true);
/* And call it by */
echo($msg['results'][0]['address_components'][7]['long_name']);
OR
2 - Using the object notation:
$msg = json_decode($msg);
/* And call it by */
echo($msg->results[0]->address_components[7]->long_name);
If you got the data back using a Google API PHP libary, it's probably not a string but an object so you can dismiss the json_decode() and use option 2. If you want to prefer using option 1, you can cast the object into an array by using $msg = (array)$msg;
In general using print_r($msg) or var_dump($msg) can be handy to debug the thing, just add your path each time you get closer to your goal. So in this case var_dump($msg) then var_dump($msg->result), then var_dump($msg->result[0]), and so on.
