How can we auto create 2nd sub-task for a parent issue when a 1st sub-task is closed for the same parent issue.

You'll need a scripting or automation tool that can trap the "close" event (either as a listener catching an event, or a post-function on the close transition).  Your script or automation can then read the sub-task for its parent and add a sub-task to it.
