First Puzzle :)

So since this puzzle is obviously a little too hard I made a second version, some questions are gone, some are changed, some are added. I didn't think so many people would have problems with Q1 but this should have been fixed since I added a lot more accepted answers for that one. I kinda wanted to keep the old Q3 tell me when you still have problems with that (remember to read the hint I already gave here).
If noone will be able to solve this until 1 day before the giveaway ends, I will edit this post to include the link to the private giveaway for you since I already bought the game^^
Oh yeah nearly forgot it, here is the new puzzle: NEW PUZZLE
Giveaway will end next week so you have plenty of time to solve it. Also: No CV required, game is worth trying I guess :)

Good luck ;)

Hints:
Q1: How are colors displayed on a monitor?
Q5: The answer is PEZhOElhNUBxJEh4JEFxNTByNENhOkFhOkF= I apparently made a small mistake encoding the answer so it was pretty much impossible to solve, sorry about that :(
Q6: A phrase you might say when you solved this freaking puzzle. I included several ones with different puntuation to cover a fairly broad range.
