Answer 1

Yes you can but you have forgotten the &s between values. You can also send data with POST method as argument to send() method. Also don't forget to use encodeURIComponent() on string values:

xmlhttp.open( "POST", url, true );
xmlhttp.send( "group="+encodeURIComponent(group)+
              "&subgroup="+encodeURIComponent(subgroup)+
              "&user="+encodeURIComponent(user) );        

Answer 2

You should add & or '&amp'; between different variables in query string like

scripts/product_transfer.php?group="+group+"&subgroup="+subgroup+"&user="+user
