There's no way to tell for sure who the main characters are in the 'Stardust graphic novel' without reading it. However, some common character archetypes might be present. There could be a brave adventurer who stumbles upon the stardust phenomenon and is drawn into a larger story. There might also be a sidekick character, perhaps a small creature or a young novice, who provides comic relief and helps the main character along the way. And there could be a powerful antagonist, a shadowy figure that stands in the way of the protagonist's goals regarding the stardust.
In Gaiman's Stardust Graphic Novel, Tristran Thorn is central. He is on a journey to find a fallen star for the woman he loves, which leads him into a world full of magic and danger. Yvaine, the star he pursues, is a main character as well. She is not just a passive object but a character with her own will and personality. There are also other characters like the princes who are after the star for their own reasons, all of which contribute to the complex web of the story.
The main characters include Tristan. He is kind of an ordinary guy at first but grows throughout his adventure in the magical land. Yvaine, the star, is a very important character. She is beautiful and has her own powers. Captain Shakespeare is quite interesting too. He seems tough on the outside but has a soft heart. He helps Tristan in many ways during his journey.
In'stardust disease fiction', the main characters could be diverse. There might be a young and brilliant doctor who is determined to find a cure for the stardust disease against all odds. There could also be a journalist who is trying to expose the truth about the disease, how it's being handled by the authorities, and what secrets are being hidden. And of course, there could be patients whose lives are completely turned upside down by the disease, each with their own story of struggle and hope.
There could be a local business owner as one of the main characters. This person would be very much involved in the economic and social fabric of the town, and thus deeply connected to the rules of the game. A teacher or a community leader might also be a main character. They would be in a position to influence the younger generation's understanding of the rules, and they themselves would have to abide by certain social and moral rules within the town.
Without having read the book, it's hard to say exactly who the main characters are. But given the title and the Texas setting, it might have a cowboy - type character who is 'back in the game' of something, perhaps a rodeo. There could also be a female lead, like a schoolteacher or a local artist, who gets involved in the main character's journey. Maybe there's an older, wiser character in the town who serves as a mentor to the others.
A 'Stardust graphic novel' could be about a lot of things. It might center around a group of characters who discover a stardust - related mystery.

It could also be about the characters' personal growth as they face challenges and make difficult decisions while dealing with the stardust mystery.
Obviously, Hiccup is one of the main characters as the title implies he is the one taming the stardust dragon.
