The main characters in 'the friendly dragon story' are likely to include the dragon, of course. There might be a group of children who find the dragon in a forest or a hidden place. One of the children could be the leader of the group, who has the courage to approach the dragon first. There could also be a villain in the story, perhaps a hunter who wants to capture the dragon for some wrong reasons, and the other characters have to protect the friendly dragon from this threat.
It's difficult to say for sure without reading the story. However, it's likely that the friendly dinosaur is one of the main characters. There may also be other dinosaurs or prehistoric creatures that play significant roles. For example, there could be an older, wiser dinosaur that guides the friendly dinosaur, or a young, curious creature that the friendly dinosaur takes under its wing. The interactions between these characters would likely be central to the story and help to illustrate the theme of friendship in the prehistoric world.
The main character is of course the friendly witch herself. There might also be some villagers, like the village elder who might interact with the witch, and perhaps some children who are curious about the witch and her magic.
Since we don't know the exact story, it could be the friendly shark itself as the main character. There might also be other sea animals like fish, dolphins, or turtles that interact with the shark and are important characters in the story.

The primary character is the big friendly giant. However, depending on how the story is written, there could be other important characters.

Or if there are other magical beings in his world, they too could play significant roles in the story. So while the big friendly giant is central, there could be a cast of supporting characters that help shape the story.
