It's important to remember that:
* Asterisms are not constellations: They are unofficial groupings of stars within a constellation.
* Constellations are not stars: They are areas of the sky that are defined by the International Astronomical Union (IAU) and contain many stars.
So, to answer your question: There are no stars in the teapot asterism itself, because it's just a pattern of stars within the constellation Sagittarius.
The Sagittarius constellation has many stars, including:
* Kaus Australis (Epsilon Sagittarii)
* Nunki (Sigma Sagittarii)
* Sagitta (Lambda Sagittarii)
* Polis (Pi Sagittarii)
* Ascella (Zeta Sagittarii)
And many others!
