The alpha star of the constellation Libra is Alpha Librae, also known as Zubenelgenubi. It is located approximately 75 light-years away from Earth. As a member of Libra, it serves as one of the key stars in the constellation, which is positioned in the southern sky and represents the scales of balance.
A constellation has several stars, at different distances. However, the only prominent star in Phoenix is Alpha Phoenicis (at just barely second magnitude), which is about 85 light-years away.
Alpha Piscium (Alrisha) is a star in the constellation Pisces.It is approximately 139 light years from us.
Alpha Arietis (Hamal) is the brightest star in the constellation Aries. It is located about 66 light years from Earth.

Eridanus is a constellation - not a single star
No, the galaxy M84 and the star Alpha Centauri are not close to each other in the night sky. M84 is located in the Virgo constellation, while Alpha Centauri is part of the Centaurus constellation. Their positions in the sky are quite far apart, so they do not align at any one time.
Any constellation is a group of stars that appear to form some kind of pattern, but have no connection with each other. They all happen to be in roughly the same direction from us, but they're all at different distances. So there's no such thing as a constellation's distance from us.
The "alpha" is a star's nomenclature means it's (usually) the brightest star in its constellation. Even if the constellations are apparently close, the stars could be any distance, since the constellation is only the two-dimensional "window" and doesn't tell us anything about the depth of the starfield. However, Alpha Sagittarii is about 180 light years from Earth. Since this is much further away than Alpha Centauri, we can more or less ignore the 4 light year distance between Earth and Alpha Centauri and say that Alpha Sagittarii is also about 180 light years from Alpha Centauri as well.
The distance to Alpha Centauri is about 4.3 light-years.
