Taurus
No, they are all stars. Planets do not "make" any constellations but they may be present around a constellation's stars. Also, the big dipper is not a constellation. It's an asterism. It's part of the constellation Ursa Major.
Leo, documented by the Mesopotamians, is one of the earliest recognized constellations. The constellation becomes visible in the Northern Hemisphere around the spring equinox , and can easily be seen through May.
Very few of the many stars that exist in our and other galaxies are not part of the designated constellations but you may be asked to look "in" a constellation to locate them. Remember a constellation is just an area of sky with some specific stars in it making a pattern, there is nothing special about it.
Cancer is most likely to be found in the spring time. Around mid April or May is the best time to view it. At 9:00 pm is when you will get the best view of this constellation.
Astronomers have debated several ideas about the significance of the Orion's Belt constellation. A popular idea is that it may have been the blueprint ancient Egyptians used to build the Giza pyramids.
