How far is alpha sagittarii from alpha centauri?
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.

What is the second star in the alpha centauri star system?
Alpha Centauri, although it appears to the naked eye as a single star, is a binary pair. Together they are designated Alpha Centauri AB, the more massive and luminous in the pair designated Alpha Centauri A, the less massive and luminous Alpha Centauri B. Together, this pair is the third brightest "star" in the night sky. There is a third star probably interacting gravitationally with the pair, Proxima Centauri, also designated Alpha Centauri C, a red dwarf which is not visible to the naked eye but is the next closest star to our Sun. Alpha Centauri B has about 90% of the mass of our Sun and is about 45% as bright. Note that Alpha Centauri B is not the "second" star (second brightest) in the constellation Centaurus: that is Beta Centauri, which is itself a trinary star system.
