Magnitudes of stars start in the negative, so the brightest star from Earth is of course the Sun, so it has an apparent magnitude of -26.74 (Note negative), whereas Polaris (The North Star) has an apparent magnitude of +1.97
See related question for differences between apparent and absolute magnitude.
The greater a star's magnitude, the brighter it appears in the sky. Magnitude is a scale of apparent brightness as seen from Earth and says nothing about how large a star actually is or how much energy it is radiating. A small star that is closer may have a greater magnitude, as seen from Earth, than a large, active star that is much further away.
A magnitude 2 star is 2.5 times brighter than a magnitude 4 star because each difference in magnitude corresponds to a difference in brightness of approximately 2.5 times.
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
The human eye can typically see stars with a magnitude of about +6 or brighter on the magnitude scale. Brighter magnitudes correspond to dimmer stars.
2nd magnitude is brighter than 3rd. 6th magnitude is the dimmest that can be seen with the naked eye; many more can be seen in binoculars, telescopes etc.

A magnitude of -5 is brighter than a magnitude of 2. The magnitude scale used in astronomy is inverted, meaning the lower the number, the brighter the object. So, a negative magnitude indicates a brighter star than a positive magnitude.
The lower the magnitude, the brighter it appears.

The 8th magnitude star is about 2.5 times brighter.
A star with a visual magnitude of 13.4 is 10 times brighter than a star with a magnitude of 15.4, because each step in magnitude represents a factor of about 2.5 in brightness.
A star with an apparent visual magnitude of 3.2 appears 1.4 magnitudes brighter than another one whose apparent visual magnitude is 4.6 .
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.
The model for measuring the apparent magnitude (brightness from earth) of a star says that a magnitude 1 star will be 100 times brighter than a magnitude 6 star (just visible with the naked eye). This means that a magnitude 1 star is 2.512 times brighter than a magnitude 2 star, which is 2.512 times brighter than a magnitude 3 star. To jump two places up the scale, use 2.512 x 2.512 as a multiplier, i.e. mag 1 is 6.31 times brighter than magnitude 3 star. To jump three places use 2.512 x 2.512 x 2.512 (or 2.512 cubed) = 15.851. So a magnitude 4 star will be 15.85 times brighter than a magnitude 7 star. Working the other way, a magnitude 7 star will appear 6.3% as bright as a magnitude 4 star (1/15.85 and x 100 to get percentage).
Good, a nice question with a definite answer. The magnitude1 star is 2.512 times brighter (near enough).
