It's hard to give a definite answer. The status of the main character's parents being alive or not largely depends on the author's creative choices and the themes and plot of the particular novel.
It depends on the specific novel. Some novels have the main character's parents alive, while others don't.
The story would be very different. Naruto's parents being alive would mean he has a support system from the start. His father could pass on his jutsu and wisdom more directly. Naruto might not have the same drive to become Hokage in the same way, as he wouldn't be seeking that family - like recognition from the village. His mother's presence would also add an element of warmth and stability to his life. And perhaps he would be more of a prodigy with both his parents' guidance, changing the power dynamics in the ninja world.
In most fanfics, the status of a character's parents can be quite variable. For this 'Harty' in the Hermione fanfic, without having read it, it's difficult to say. It could be that the author decides to keep them alive to have a support system for Harty or perhaps to create a contrast with Hermione's own family situation. If the fanfic is about Harty's adventures in the wizarding world similar to Hermione, having living parents could mean they are either muggles who need to be protected from the wizarding threats or they could be wizards themselves and be part of Harty's journey.
One possible scenario in such a fanfiction could be that Naruto's parents are preoccupied with their shinobi duties. They might be constantly on missions for the Hidden Leaf Village, leaving Naruto at home with caretakers who don't really pay him much attention. This could lead to Naruto feeling lonely and isolated, just as he did in the original story when he thought he had no family.
He would be more confident. Growing up with his parents' love and presence would mean he doesn't have to constantly seek validation. So he might be less brash and more self - assured from the start.
The main character Wang Lin's parents didn't survive the novel. Wang Lin's father, Wang Zhuo, was a mortal who was killed by Teng Huayuan. Wang Lin's mother, Li Muwan, was a member of the ancient Li family on planet Suzaku. She married Wang Zhuo and died shortly after giving birth to Wang Lin.

Peter might be more confident. With his parents alive, he has a support system. They could guide him, which might make him less impulsive. He may not have to figure out everything on his own like in the original story where he's on his own. So his decisions could be more thought - out.
Naruto would likely become more determined. His usual goal of becoming Hokage might be put on hold as he focuses on rescuing his parents. He would train harder, pushing his limits to gain the strength needed to face the kidnappers. This would accelerate his growth as a ninja.
Tony's personality could be more balanced. His father's discipline and his mother's kindness would have influenced him. He might be less cocky and more collaborative. For example, in dealing with other superheroes, he would be more likely to listen to their ideas rather than just pushing his own plans forward.
His confidence would grow. Knowing he has his parents' love and support directly would make him bolder. He might not be as quick to jump into dangerous situations on his own.
Naruto would be more self - assured. In the original, he was always seeking approval because he was an orphan. With his parents alive, he'd have that unconditional love and support, so he wouldn't be as desperate for others' recognition.
