Antares
Antares is a red supergiant star and not a constellation or an asterism.
Hypergiants are super luminous supergiants. It isn't all about sheer size. Eta Carinae is a hypergiant but it is smaller than the supergiant Antares. This is due to the fact that Eta Carinae is about 60 times as luminous as Antares and 10 times as massive. Although size doesn't matter, the largest star VY Canis Majoris is a Hypergiant.
Star Arcturus has a temperature of around 3,700 to 5,200 Kelvin.
No. Arcturus is believed to be a single star.
