yes constellations are relative in comparison with where you are located in the universe. depending on where you travel some constellations may stay the same while other will drastically look different.
To the nearest Star
Constellations are used for navigating. Since different constellations appear in different parts of the world at different times of the year, if you know the approximate time of the year you can figure out where you are by the constellations.
They're generally named for the constellation they appear to originate from. For example, the Leonids appear to radiate from a location in the constellation Leo, and the Perseids from a location in the constellation Perseus.
Earth revolves around the sun. That is why the constellations we see from Earth appear to change.
During the year, due to the earth's orbit, different constellations appear during different seasons. You can use the constellations to determine the time of year.
The Earth's rotation causes the constellations in the night sky to appear to move across the horizon. This rotation causes the constellations to rise and set at different times throughout the year, leading to different constellations being visible during different seasons. Additionally, the Earth's atmosphere can cause the stars to twinkle and appear less bright or crisp, depending on factors such as air pollution or atmospheric conditions.
It would only change very slightly. You would need instruments to detect that small of a change.
No. Constellations are arrangements of stars that appear to form pictures.

after sunset and before sunrise
Stars and constellations appear to move in the night sky because the Earth is rotating, while the stars and constellations stay there.
because in april we are at a different point in the galaxy, therefore we see different stars. Also, April is in spring and june is in april
