[Puzzle]Thomas Was (Not so) Alone

Hi there !

For this giveaway, I wanted to make a simple puzzle. All the answer can be find easily if you know what to look at.
You can win Thomas Was Alone and there is no contribution value required.

As for every puzzles, common rules apply. Don't share hints or answers please, there is really no need for this. And if there's a leak, I will simply delete the giveaway.

I hope you will enjoy it. There are just 5 questions about couple of things I have learned over the past year.
I will not be able to provide much hint during the upcoming hours but I will be there to help you if needed later. :)

And now, the most important : Easy puzzle is easy.

Edit : changed Q1 text so it's less confusing and also less easy. The answer was in the question. Also added some answer possibilities, hope it helps.
