1. Do not add "for"
2. "I met" is correct
3. The first sentence is correct
("What is mary's favorite color?" is more simple and direct. However, your sentence could be appropriate if you were looking at a group of several colors and trying to determine which one of them was her favorite color.
4. Use #2 or #4
5. He went to Thailand...
6. Ask Jenny if the fridge is John's?
Ask Jenny whether the fridge is John's or not?
(I never heard a rule about this. However, I know what sounds right.)
7. This is a complicated question. I am providing you with some links to explain the difference of past tenses.
Basically, the choice depends on the context.
