yes
Yes, drinking water does boil at a lower temperature than salt water.

salt helps to bring the water to the boil faster.
makes it boil faster
No, salt water does not boil faster than water with pepper. Adding salt or pepper to water may change its boiling point slightly, but the difference is not significant enough to affect the time it takes to boil.

Yes
salt has to break down first
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Boil the water (and condense it if you want to keep it) and the salt will be left behind
possibly...
