A constellation is a group of stars as seen from where we are. The same constellation would look different from somewhere far away. Each star is a big ball of hot gas which emits heat and light to get rid of the energy produced inside by nuclear reactions, mainly hydrogen converting to helium. A planet is a much smaller object without its own light, which goes round a star in an orbit.
The star or constellation often confused with the planet Mars is Antares, which is a red supergiant in the constellation Scorpius. Antares appears bright and reddish in the night sky, similar to Mars, which can lead to confusion between the two celestial objects.

Every constellation has different stars, no star is in all of them.
A star is a single body, and a constellation is a group of stars.
That would depend on where you looked at it from. All constellations depend on where they are seen from. If our planet were orbiting around a different star, most, if not all the constillations would look different. If you are on the Earth, it's not in any constellation.
A star is an individual body like the sun, a constellation is a cluster of star systems.
Depending on which constellation, somewhere between then next 20 and 2000 years people will see that star explode; the constellation will appear different for a year or five, and then disappear, leaving a whole in it.
The 15th star in a constellation group will vary depending on which constellation you are referring to, as each constellation has a different number of stars. It would be helpful to specify the constellation in order to determine the 15th star.
VV Cephei is a star system, not a planet. It is a binary star system consisting of two massive stars, one of which is a red supergiant. The system is located in the constellation Cepheus.
Gliese is not a planet; it is a star. Specifically, it is a red dwarf star located in the constellation of Libra. There is ongoing research to discover planets that orbit around Gliese.
'cause the star is self luminous and the planet is not .
