Can a car run without a battery once started?

Unless your battery was also fscked you should’ve been able to go a lot longer than 5 minutes before your engine died. and in response to the question, yes a car can run with a dead battery, or a dead alternator (as long as the battery still has some charge), but not if both are dead.
