Question mark?

Here are a few keys that I have replaced the actual number or letter with a question mark, I saw someone else on the forum do it (I forgot who it was) and I decided to do it because I can't come up with a good puzzle.

The keys:

TAKEN - Fortix 2 - HV?V2-?F0EW-TVPNC (First question mark is a letter between F and N. Second question mark is a single digit number)

TAKEN - Your Doodles Are Bugged! - ?DLTY-4L30A-QTJ9? (Both question marks are single digit numbers)

TAKEN - Hacker Evolution - ?A7IJ-ZHE8H-A85E? (First question mark is a letter between A and M. Second question mark is a letter between E and N)

TAKEN - Hacker Evolution: Duality - 6GJ??-DHYRB-L7354 (The two question marks represent a double digit number that is the same number twice Example: 77 or 00)

TAKEN - Hacker Evolution: Untold - 6EW5?-B8MX0-P?GQC (First question mark is something you do in a restroom. Second question mark is a letter between A and Z)

Also if you get a key please say you got it so no one will waste their time trying to get a key that is taken.
