Definitions:

• Size (Solar Radii): The star’s radius compared to the Sun's.
• Brightness (Apparent Magnitude): How bright the star appears from Earth (lower numbers = brighter).
• Distance (Light-Years): The distance between the star and Earth, measured in light-years.
• Absolute Magnitude: The star’s intrinsic brightness if placed 10 parsecs (32.6 light-years) away.

Altair, Vega and Deneb make up the Summer Triangle. Inside of which and overlapping is the Northern Cross aka Cygnus the Swan.

[HandyDandy]

Unfortunately, but just as the article says, Polaris, the North Star, is not very bright at all! However it is still easy to find because it is the tip of the tail of the Little Dipper. The two end stars of the dipper of the Big Dipper line up to point to it. Those two stars are known as the pointer stars.
Also, the “handle” of the Big Dipper is curved (like an arc). If you follow that arc it will lead to Arcturus (hence the expression “arc to Arcturus”.)

[HandyDandy]

It doesn’t look it in the photo collage but Vega is definitely blue in the real night sky. It is directly overhead in the Northern Hemisphere during Summer. It is a star in Lyra, the Harp. Definitely blue unlike white as in the collage.

[Srednik]

Yes. These “first magnitude” stars have been used by mariners for thousands of years.

Srednik once had a shipmate who was an amateur astronomer who taught him the names of the main “navigation” stars. In evening and morning twilight, using a sextant, the mariner can measure the altitude (angle of star above the horizon) because both the star and the horizon are visible. Each star will yield an “LOP-line of position” and where these LOP’s cross, “BINGO!” you have the position of your ship at the (adjusted for each observation) time of your sextant work.
