Well, first of all, Natsu would probably be excited to see himself in all kinds of wild adventures in the fanfiction. He loves action and if the fanfic has him in some epic battles, he'd be all for it. Lucy might be a bit more critical. She'd look at how she's portrayed in terms of her intelligence and her relationships with the other guild members. Gray would likely be cool about it, but might get a bit annoyed if the fanfic made him seem too cold or too goofy. And Erza would be very strict in her assessment. If the fanfic doesn't adhere to the values of the guild she holds so dear, she might not be too happy about it.
The guild as a whole would likely mobilize. Erza would start formulating a strategic plan. She'd consider the strengths and weaknesses of Acnologia and figure out the best way to approach the situation. Gray would also be ready to fight, using his ice - make magic to support the rescue mission. They would all be united in their determination to get Lucy back safely.
The Fairy Tail guild would probably be very curious about Naruto at first. They might be amazed by his strange abilities like running up walls and creating clones. Some members, like Lucy, would likely be a bit cautious, but also intrigued. Natsu would probably be eager to test his strength against Naruto right away.

In the 'Fairy Tail Watching the Future' fanfiction, it might show the characters seeing a future with new magic that they don't understand. This could make them curious and eager to learn about it in the present. They could also see a future where relationships within the guild have shifted, like a couple that doesn't exist in the present time is formed in the future. This would surely stir up a lot of emotions and discussions among the guild members.
It could also be about the Fairy Tail guild making decisions based on the future they see. They might change their current actions to avoid a bad future or strive to achieve a better one.
