Thak you for your question.



Andromeda is a constellation named for the princess Andromeda (which is Greek for Ruler over men), a character in Greek mythology. The constellation is in the northern sky near the constellation Pegasus. It is most notable for containing the Andromeda Galaxy. It is sometimes called "The Chained Maiden" in English.



Corresponding Chinese constellations in Andromeda are Flying serpent (螣蛇), Celestial stable (天廄), Wall (壁), Legs (奎), Southern military gate (南軍門) and Great general of the heaven (天大将軍).



The brightest star in the constellation is Alpheratz (Sirrah in the image), which marks her head, Bayer designation Alpha Andromedae. Formerly considered common to Andromeda and Pegasus, as confirmed by its name, "navel of the horse", it was also designated δ Pegasi. With α, β, and γ Pegasi it forms an asterism called the Great Square of Pegasus.



Xi Andromedae (ξ And / ξ Andromedae) is a binary star in the constellation Andromeda. It also has the traditional name Adhil, from an Arabic phrase ????? ae-eayl meaning "the train [of a garment]" (literally "the tail").



β Andromedae is called Mirach, the girdle. It is 200 light years distant and of magnitude 2.1.



γ Andromedae, or Almach, is found at the tip of the southern leg of the big "A". It is a beautiful multiple star with contrasting colours. Is this what you meant by Almaal. Gamma Andromedae (γ And / γ Andromedae) is a four star system in the constellation Andromeda. It is also known by the traditional name Almach (also written as Almaach, Almaack, Almak, Alamak). It is known as 天大將軍一 (the First Star of the Great General of the Heaven) in Chinese.



I have attached sources for your reference.
