Answer 3

Only and only if the timing requirements are met. You cannot activate set Trap cards for no reason, so you cannot chain Mirror Force, Sakuretsu Armor, etc. as they would have occurred at the Battle Phase. So the only time to activate set cards is if you have a Trap card that can negate Heavy Storm or Mystical Space Typhoon, such as Judgment of Anubis, Solemn Judgment, Dark Bribe, etc. and/or if you have cards that can be activated during the whole TURN or at that phase (Battle Phase, etc.), Threatening Roar, Blast with Chain (if there is a monster on the field), Waboku, etc. The only time that you cannot chain activate set Trap cards is when I just mentioned, the wrong timing on the card (such as Magic Cylinder requires your opponent to attack, so it can never be chained to Heavy Storm) or the during the turn you have just set the Trap card (I set Waboku for this turn, you chained MST, I cannot activate it).

However note that if Trap cards have the effect of "If this face down card has been destroyed and sent to the Graveyard" it stills work during the turn that the card had been set, eg. I set "Statue of the Wicked" you chained MST, I special summon tokens by it's effect, because it had been destroyed face down.
