[Star Wars] When Jedi fail to deflect a blaster bolt and get shot, what exactly went wrong? Is it purely getting overwhelmed by too many bolts, or did the Jedi panic and lose their foresight?

It could be either.  Even Jedi have their limits of concentration, and a lapse of just a second - a tiny distraction that they succumb to - can be enough for something bad to happen.  

Of course, even with perfect concentration, limits are limits.  A lightsaber can in theory block two blaster bolts fired at the same time - angle it the right way, and you can always hit two (as long as they're close enough to hit).  Three at the same time would be impossible to block, unless they all happen to fall along one line - meaning the Jedi must move their body to dodge along with (or instead of) blocking.  Add in more bolts at once, and that job becomes tougher and tougher.  Past a certain point, awareness, ability, and (basically) precognition can be overwhelmed by brute force.
