I've been seeing a lot at the start of a title of a thread it says [FAQ], I used to think it was AK only, but now I'm seeing normal users do it, how do they do it?

The [FAQ] tag can only be administered by forum staff, but they can do it to any thread, whether they wrote it or not.
The tag lets forumites know that it is an important thread for whatever reason, as well as prevents it from being munched.

Normal users don't do it.
If you check the first posts you can see that an AK edited and said something like "FAQed!".
ArchKnights "tag" a thread with the [FAQ] thing to keep it away from forum purging and to list them as helpful threads.
