It would only change very slightly. You would need instruments to detect that small of a change.
To the nearest Star
The actual boundaries of the constellations do not change, but because all stars are moving, the shapes appear to change. e.g. Ursa Major (the Big Dipper) will be a different shape in 100,000 years as the stars that comprise it are all moving relative to each other.
why do they change
The constellations change position because of the same reason the days range in length from summer to winter. The Earth's tilt and wobble. The constellations stay in the same place in the sky, but every day the Earth moves while the tilt stays the same, leaving it to appear that the constellations have moved. (It's better to understand with a picture..)
Star constellations are the different patterns that the stars in the sky make up. They do not change their shape.
Earth revolves around the sun. That is why the constellations we see from Earth appear to change.
Yes, the constellation Eridanus appears to move across the night sky due to Earth's rotation. It generally moves from east to west as the night progresses. This motion can vary slightly depending on the time of year and your location on Earth.

Does the question mean the distance between two stars? It does change, but very slowly on a human time scale. In 100,000 years most of the familiar constellations will look quite different.
yes it have 5 star
Constellations are made up of star patterns. Over tens of thousands of years, as the stars move and slowly change their locations, new constellations may appear. Since stars are technically "matter" AND they are in the Milky Way Galaxy, I suppose the answer to your question could be "maybe". What do you mean by "matter" ?
Ultimately, all constellations come from the human imagination. Constellations are purely a matter of perception. Most of the stars in any given constellation are nowhere near each other and have no true connection. If you change your perspective enough, the constellations would entirely change.
