reading separate inputs on digital pins, storing order and replaying as output

Projects Programming
3 
    digitalRead(D);
    digitalRead(E);

This doesn't achieve anything. You need to store the results, eg.

  a = digitalRead(D);
  b = digitalRead(E);

      firstInput;
      secondInput;
      thirdInput;
      fourthInput;
      fifthInput;

What does that do?
