Order of Alert Popups/Messages

Hi guys, I have the code here and working fine except for the order of the alert popups/messages. I want the alert popups to be in the order of from top to bottom as it's shown in the browser. If you click Submit button without ticking any radiobuttons, you'll see what I mean.

Will you kindly help me out? Thanks guys.
