Let the user guess multiple times on stages 3 and 4

If the user guesses wrong, red alert should be shown for wrong answer (Wrong! Try again. 1/3) and the user should be allowed two more guesses at the answer. I'm not sure if this should be an optional feature or default behavior.

Adding it as an optional feature would probably be the best option. If not just adding it as a setting to the quizsetting.js file with it set to 0 as a default value could also work.
