Well, it might also mean that out of all the Twilight fanfics out there, only five were really significant or had a particular impact. Say, in terms of influencing how the Twilight fandom views a minor character. These five fanfics could have been the ones that really delved deep into that character's backstory or motives, and thus, only five were needed to change the general perception.

I read one where the Five Guys run a sort of underground network in Twilight. Bella gets involved when she's trying to find out more about Edward's past. They help her dig deeper into the vampire lore and she in turn helps them with some human - related issues they're facing in the town. It's a really engaging story.
Twilight is not a fanfic. It was developed independently by Meyer and became a highly popular series. The story, characters, and plot are all original creations of the author.
