I am asking about the red circled ends of the handrail.
How much should they extend beyond the contact point between the supporting posts and the contact point near the end of the handrail?

As far as I know, none. The handrail needs to return to the wall/post to avoid a catching hazard. This is specified in IRC (2014?) 311.7.8.2:
Ends shall return to wall or terminate in newel post or safety terminals
When I replaced a handrail and chatted with the AHJ, they suggested this was mainly for firefighters, who have a lot of gear that might snag on a handrail and who operate in dark, smoke filled buildings and are in a hurry. But anyone who caught a bag on a protruding handrail will appreciate the return.
