To understand special relativity you must think clearly.
1) If Flash runs at the speed of light for 5 minutes STOP
5 minutes in whose frame of reference?
a) In 5 minutes in the earth's frame of reference, the Flash would age 0 minutes.
b) In the frame of reference traveling at the speed of light, time does not progress. You can't spend 5 minutes traveling at the speed of light!!!
This makes no sense, so perhaps you mean this question.
2) If Flash runs near the speed of light for 5 minutes (by his watch), how much time would have passed when he is finished?
The answer is that any amount of time between 5 minutes and infinity could have passed depending on how close the Flash was to the speed of light.
However, there is no where on earth that would take 5 minutes traveling near the speed of light, only seconds. That length of time is on the order of traveling to the Sun.
