Since I haven't read the novel, I can't say for sure. But it could be the dancing girls themselves, their instructors, or people related to their dancing careers like choreographers or managers.
There's no way to know for certain without reading the novel. However, it would be reasonable to assume that the main characters are the dancing girls. There could be a lead dancing girl who is the focus, with her friends or rivals among the other dancing girls also being important characters. And if the novel has a romantic sub - plot, there could be male characters who are in love with the dancing girls or are somehow connected to their personal lives outside of the dance world.
I don't know precisely, but it's likely that the main characters would include the most talented or prominent dancing girls in the story. There might also be a character who is an outsider but becomes involved with the dancing girls in some way, perhaps a journalist who wants to write about their story or a new student who joins their dance troupe and shakes things up.
The main characters are probably the dancing girls themselves. They would be at the center of the stories, with their unique personalities and stories to tell.
I'm not sure specifically without having read the novel, but it's likely that the dancing girl is one of the main characters. There might also be a love interest, like a young man who is drawn to her because of her dancing or her unique charm.
There could be a character who witnesses the dead man dancing.

In the 'dancing with dragons ya novel', the main characters could include a young hero or heroine. This character might be on a quest, and the dragons are either obstacles or keys to achieving their goals. There could also be an antagonist who wants to use the dragons for their own evil purposes. And perhaps a group of side characters, like the hero's friends or family, who support or are affected by the hero's actions regarding the dragons.
The key characters could include not only the dancing girls but also those around them, like their managers or instructors if there are any in the stories. Their families might also be important characters as they could influence the dancing girls' lives and decisions. For instance, a strict father might oppose a girl's dancing career, creating conflict and driving the story forward. Also, there could be other characters in the dancing world, such as rival dancers, who add to the drama and development of the plot.

And of course, there may be others with their own quirks and qualities that together form the core of the story.

Maybe there's an old sage who knows the secrets about the dragon's dancing and plays a role in the story as well. Another possibility is a group of forest creatures that are either friends or foes of the dancing dragon.
Maybe there are other characters like an audience. In a story, the reaction of the audience to the dancing girl's performance can be important. There could also be a love interest. For example, a young man who falls in love with her at first sight when she is dancing on the stage. And perhaps there is a rival dancer who is jealous of her talent and tries to undermine her.
