Answer 1

It means that you are trying to access an item in an array with an index higher than the limit of the array.

Answer 2

It means that you are trying to access an index bigger than the array. In the line:

while(playedThisRound[index] == false)

You don't check the boundaries before using the index, and your crash is probably there.

Answer 3

i is within the bounds of nPlayer length not 0-4.

public Player[] getWinner(Player[] nPlayers)
  {
      int maxScore = 0; //edit
      Player[] winningPlayers;
      winningPlayers = new Player[5];
      for (int i = 0; i < nPlayers.Length; i++)
      {
          if (nPlayers[i].wins >= maxScore)
          {
              winningPlayers[i].wins = nPlayers[i].getWins();
              winningPlayers[i].name = nPlayers[i].getName();
          }
      }
      return winningPlayers;
  }
