4.02 m, 4.00 m, 4.06 m, 4.05m. Are these measurements accurate, precise, neither or both?

Insufficient data.

Imagine a target with bullet holes. Bullets from one rifle are all over the board, but all within the largest ring. Bullets from a second rifle are tightly grouped at the outside edge of the largest ring. The bullets in the first group are all closer to the bullseye than any bullet in the second group. That is accuracy. The bullets of the second group are closer together than the first group. That is precision.

Precision means the same result every time. Accuracy means closer to the right result every time.
