4 Previously answered as Amsterdam as it was the first where women athletes competed(though they had been in other sports) and the first to have an olympic flame over the stadium.
The answer to 2 must be either Helsinki or Montreal because they are the only host cities with eight letters. Unless we're including the winter games in which case it would be either Chamonix, Grenoble or Sarajevo.
I can't see a connection with any of these cities and the clue.
