Most tour companies will allow bottled water on tour, but the museum's may have their own policies. Bring a bottle of water, dehydration is no joke.
Varies on the tour. They may ask you to throw it away if its pop but water should be fine. Some will ask you to leave it in a specific room and not take it through the house.
We had water bottles with us...we were simply told not to touch any items in the homes...
Not really sure. Probably varies by tour operator
