Fallout shelter iPhone app, do people dwellers waiting to enter vault affect the food and water levels?

No. Only dwellers that are in your vault affects your water, food, and electricity.

No. They don't affect food and water until they enter the vault. Similarly, any dwellers that are out the vault on a quest or out exploring won't use up food/water in the vault for the duration they are outside.
