4. The Three Types AJAX Uses XHTMLRequest to pass XML
Very well known and understood
Big, bloated files

5. AJAX
JSON
JavaScript Object Notation
var myObj = eval( '(' + jsontext + ')' );
Or, safer:
Compact, but still becoming popular
It wouldn't surprise me to see this be standard next year.

6. The Three Types
AJAX
JSON
PHP?

7. The Three Types AJAX JSON PHP Yep, that's right:
$text=unserialize($textFromService);
Yahoo's web services (output=php)
Not really for Async, but more for PHP to WebService communication

8. The Three Four Types AJAX JSON PHP Google's GWT RPC
More on this later...I don't think we can use it at the moment anyway.
