The neighbors could be in the story too. Quagmire, for instance. Peter might tell a story about how Quagmire got into a really embarrassing situation and how they all helped him out (or made it worse). Or he could include Cleveland and tell a story about a neighborhood barbecue gone wrong because of something Cleveland did.
The main characters are the princess and the miner boy. And of course, the goblins are also important in the story as the antagonists.
The main characters are the princess and the prince. There's also the queen who tests the princess to see if she's a real princess by placing a pea under a stack of mattresses.
Well, of course, there is the princess. She is often portrayed as brave and gentle. And then there's the frog. He has his own charm despite being in the form of a frog. There might also be some side characters like the voodoo man who cast the spell on the prince, but the princess and the frog are the central figures.
The main characters are the princess who is turned into a swan and the prince who tries to save her.

In 'The Little Mermaid', Ariel is the mermaid princess, the main character. There's also Ursula, the sea witch, and the human prince she falls in love with. In 'Beauty and the Beast', Belle is the beauty and the Beast is, well, the beast. Gaston is the villain who tries to stop Belle from being with the Beast. All these characters interact to create the engaging plots of bedtime princess stories.
The princess herself is a main character. She is often depicted as kind, brave and curious.
The princess and the dragon are the mainstays. The princess can range from a damsel in distress to a strong - willed heroine. She may have special powers or just her wits. The dragon can vary from a huge, scaly brute that everyone fears to a more complex character with a backstory. There could also be side characters such as the king and queen who worry about the princess, or a wizard who gives the princess advice on how to deal with the dragon.
