Answer 1

1. I'd use one of these phrases instead of "telling-a-lie" --

the Liar's Contest
the Biggest Lie Contest
the Best Liar's Contest

2. OK
2-2. Who was the biggest liar of them all?
3. OK
4. OK
5. Awkward. Better might be this:
<i>With his lie, the old man puzzled the king and was able to win the golden apple.
