Rigel is hot by "normal" stars but it is not the hottest, this distinction goes to a star named Cygnus OB2-12. See related questions.
Yes. Rigel is the right leg of the constellation Orion and is the 6th or 7th brightest star in the sky. Rigel and all of Orion are best seen in Winter (Summer for the Southern Hemisphere) and are close to directly overhead at around 10:00 PM at Christmas. Rigel can easily be found by locating the Red Supergiant Betelgeuse (10th brightest star in the sky) and the three stars that make Orion's Belt. Rigel is a Blue Supergiant, one of the largest and hottest types of stars.
Rigel in Orion and Deneb in Cygnus are such examples

Orion is a prominent winter constellation visible in the night sky from both hemispheres. It is recognizable by its distinctive three-star belt and includes some of the brightest stars in the sky such as Betelgeuse and Rigel. Orion is best seen during the months of December to March.
Rigel is a blue supergiant star with a diameter of about 78.9 million miles (126.5 million kilometers), which is roughly 70 times the size of the Sun. Its surface temperature is around 12,100 Kelvin, making it one of the hottest stars visible to the naked eye.
Rigel is approximately 860 light-years away from Earth. Since a light-year is the distance light travels in one year, it would take light from Rigel 860 years to reach Earth. This means that the light we see from Rigel today actually left the star around the year 1160 AD.
The Little Dipper contains the north star, so if you're in the northern hemisphere, it should be visible any time of year.
This all depends on location, assuming that you are in the Northern hemisphere, it can be seen between early January to mid-march in the night sky.
