No. There is no such thing as magic.
There is nothing you can do to storm a tornado.
No

No, you cannot stop a tornado with another tornado. The two tornadoes would simply merge and form a larger tornado.
There is no known way to stop a tornado.You cannot stop a tornado. It is a force of nature.
No, note the difference between 'negate' and 'destroy'. When 'Magic Cylinder' activates, it doesn't matter what happens to the 'Magic Cylinder' card, it will not stop the activated effect from resolving. Chaining 'Dust Tornado' to it will do nothing. What you need is a card that will negate the effect too, such as 'Trap Jammer' or 'Solemn Judgment'.

No.
No, Dust Tornado is a destruction card but not a negation card.
No, lightning has little to no affect on a tornado.
No. Water does not stop tornadoes and a tornado could easily capsize and even lift and throw a small boat or heavily damage a large one.
Within their own universe that is, to some degree, governed by cartoon physics they probably could. They probably could not stop one operating on real-world mechanics.
