This question is prompted by a previous question ( When did Bilbo and Frodo learn that Gandalf was a Maia? ). My initial instinct was that Bilbo and Frodo had no idea what a "Maia" or "Vala" was. They probably knew more than the average Hobbit about these things, but I would guess they know less about their own universe than average readers of Tolkien legendarium questions on this site.
This question ( How well-known is the theology of Middle-earth, in Middle-earth? ) establishes that Faramir's men know of the Valar. One cries "May the Valar turn him aside!" when faced with an oncoming oliphant. Being Men of Gondor, which has a long history, they probably knew more than other Men or Hobbits. Clearly, many of the Elven characters (Galadriel, Elrond, Glorfindel, Círdan, etc) are also well aware of the Valar and Maiar and some of them were present for the events of the First Age.
Is there any evidence from the books or Tolkien's writings that the Hobbits had a good understanding of their own creation story? Do the Hobbit characters of Lord of Rings or the Hobbit discuss Vala, Maia, or events of the First Age, beyond simply recognizing that there are old, mysterious powers in the world that mostly outside of their experience and knowledge?
