A short puzzle (ends December 13th)

Cool
I did solve the puzzle minus 2 and 3, so xD

Edit to add:
I'm interested in the answers but not the GA, so I'll check back later when it's over and the answers are published.

Found him through some googling. Thank you for the hint! Any tip for the third question? I cannot figure it out.

Update
I finally got it! The “three words that shocked the audience” was throwing me off. It might be more than three, actually haha. You could swap it for a different hint if you think that’s a good idea. Thanks for the awesome puzzle and giveaway, by the way. Have a good one!

Thank you very much! After several tries I realized who it was (^_^)

Bugged website, finally did it.
