If you were standing on the equator, how many circumpolar stars would you see?
At the equator, you will see no circumpolar stars.
No. All circumpolar constellations are found near the celestial poles. Because of their proximity to the poles, they never disappear from view. Sagittarius is on the ecliptic and thus (like all other zodiac constellations) not close enough to the poles to render it circumpolar.
Circumpolar constellations are those that never set below the horizon. The further north (or south) one travels, the more constellations are circumpolar. Where I live, above the 45th parallel, most of the Big Dipper stars are circumpolar, but Arcturus is not, and the constellation of Orion sets below the horizon in the summer. Equatorial constellations are those that pass directly overhead when one is between the tropics of Cancer and Capricorn. I believe these are primarily the 13 constellations of the zodiac.
Most natural celestial objects do this; exceptions would be any fixed star that is 'circumpolar'-- they are close enough to the celestial poles that they never appear to dip below the observer's horizon. Which stars are circumpolar depends on the latitude of the observer.
If you are right at the Equator, you will not be able to see Polaris. If you could, it would be right on the horizon, but ground haze and obstructions would almost certainly hide it from view.

All stars are circumpolar
Nothing seen in the sky from a point on the Equator is "circumpolar", meaning that everything in the sky appears to rise and set.

At the North Pole, and at the South Pole.
Subtract your latitude from 90° and that will give the the decollation of circumpolar stars. In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.
They believed that when Paraohs died they would become one of the circumpolar stars

The region of the sky visible all year round is called "circumpolar". What stars and constellations are included there depends on your geographical location. For example, for somebody living 30 degrees south of the equator, a region around the south pole of the sky, with a radius of 30 degrees, would be circumpolar.
gemini is not circumpolar. the circumpolar constellations for the northern hemisphere are Cassiopeia. Ursa Minor, Draco, Cepheus, and Ursa Major.
Beautiful question !! Circumpolar stars and constellations are stars and constellations the "go around the pole" = Circum (circle) polar (the pole) The North Star is called "Polaris" because it's directly above Earth's North Pole - in other words, if you went to the North Pole, "polaris" would be directly over your head. Because of this, all of the stars appear to pivot around Polaris as Earth rotates. Now I don't know where you live, but if you live in the United States, Polaris would NOT be overhead - it would be lower in the sky but still in the North. The lower on the globe you live, the lower Polaris appears in the sky. So, the stars and constellations that spin around Polaris but DON'T SET, are called circumpolar stars and constellations.
