HD37605 with an apparent magnitude of 5.53 may be the dimmest named star. However, there are many, many stars in any given constellation which are too dim to see even with a powerful telescope, so in a sense there's no "dimmest star".
Alpha Andromedae (Alpheratz, Alpherat, Sirrah, Sirah), is the brightest star in the constellation of Andromeda with an apparent magnitude of between +2.22 and 4.21 (This is because it is a variable star)

Ursa Minor or the little bear hassix main stars.

One estimate for the number of stars in the observable universe is about 1022. Ursa minor covers about 0.62% of the sky, so that would mean there are around 6x1019 stars in Ursa Minor, nearly all of which are far too faint to see.
The question indicates that you don't know what a constellation is. A constellation is not a "picture" or pattern of stars in the sky (that would be an asterism); a constellation is a defined patch of the sky with definite borders and contains literally billions of billions of stars.
There are 7 stars in the "little dipper" asterism in Ursa Minor, if that's what you were trying to ask.
There are several. Which one you're referring to depends on how bright, how near,
and in which direction.
If you're looking southeast of Orion ... below and to the left of his right foot, as seen
in the northern Hemisphere ... then you're looking at the single brightest star in the
night sky (ignoring the sun, moon, and planets). That's "Sirius", sometimes called
the "Dog Star" after its position in Canis Major ... the "Big Dog".
Ursa Minor is a constellation ... a collection of individual stars that appear to form a pattern
in the sky because of their positions. The stars of a constellation have no connection or
association with each other. Each one has its own individual color, temperature, size, and
distance from our solar system.
There are 3 main stars in the constellation Andromeda.

Betelgeuse is the second brightest star in the constellation Orion.
Not a very exciting name but 46 Leonis Minoris is the brightest star in the constellation Leo Minor.
Ursa Minor, the little bear
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.
Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major.It is approximately 81 light years from us.
Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major (Big Dipper).It has a spectral class of A0 which means it is a white to white-blue star.
Polaris is the brightest star in Ursa minor but that does not necessarily mean that it is the biggest.
Polaris (North Star)
The brightest star in Ursa Major is a star called Alioth.
Polaris is the brightest star in the constellation Ursa Minor.
The North Star (Polaris) is the brightest star in the constellation Ursa Minor and the 45th brightest star in the night sky. Its temperature is 6015 K.
Ursa Minor, also known as the "smaller bear," originated in ancient Greek mythology. The brightest star in the constellation is Polaris, also known as the North Star.
Polaris (the North Star) is the brightest star in the constellation Ursa Minor (the little bear).
Ursa Minor, also known as the "smaller bear," originated in ancient Greek mythology. The brightest star in the constellation is Polaris, also known as the North Star.
Polaris is in the constellation Small Bear (Ursa Minor). I didn't check whether it actually is the brightest star in that constellation.
Ursa Minor is a constellation not a star
The primary star in a constellation is called the "Alpha" star - it's almost always the brightest one in the constellation. "Beta" is the second brightest, and it follows the Greek Alphabet as the stars get dimmer... Polaris is the North Star located in the constellation Ursa Minor - the Little Bear.
Yes, it's the alpha-star in Ursa Minor.
