  1.  
  2. is it possible that 1 electron absorbs enough energy for example 3 times the threshold frequency and collides with another electron and transfers some of its energy to other electron which is more than the threshold energy and both the electrons are ejected?

    Ans 1 ->
    depends upon the work function of the metal. but if we consider your case we might contradict the second condition which states that each photon can at the most eject one electron. nice question btw.

    Ans 2 ->
    but yes as sir said we consider that no time lag exists so the electrons will be ejected out almost instantaneously without colliding with other electrons
