Four ways to score exactly 5 runs: (1) Running 5 runs (rare, requires overthrows), (2) Boundary 4 + 1 run (batsmen cross), (3) No-ball called with boundary-4 (5 runs: 4 from boundary + 1 penalty), and (4) Penalty awarded (5 runs) for various breaches. Overthrows can convert any shot into 5 runs if the ball travels to boundary after being chased.
