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.
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.
Divide the diameter of the galaxy by the diameter of Earth. Since it seems you want to compare the volumes, raise the result to the third power. This assumes the galaxy is spherical - which in a way it is, if you consider the halo of star clusters.
In Jan 1987, John Cormedy of Dominion Astrophysical Observatory in Canada discovers the balck hole in Galaxy Andromeda and estimated that the diameter of black hole in Andromeda Galaxy is 10 million times as massive as the Sun.
It's a dwarf galaxy; the diameter is about 6500 light-years (according to information in the Wikipedia article).

Our galaxy, the Milky Way, has a diameter of about 100,000 light-years.
The dwarf galaxy is about 8,000 miles in diameter.
An average dwarf galaxy is small in diameter.
The average diameter of a dwarf spheroidal galaxy is 10 kiloparsecs.
Unknown.
M84 is the largest even number.
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.
When compared to the diameter of the Milky Way galaxy,the diameter of our solar system is very nearly zero.
The Andromeda galaxy is approximately 220,000 light-years in diameter. It is the closest spiral galaxy to our Milky Way galaxy.
Our galaxy is a barred spiral galaxy. There is a bar of stars, like the diameter of a circle, from which the spirals emanate, so to speak.
