Believe it or not, the brightest stars in the sky are NOT always the largest. There are several different types of stars. Red giants are the largest that I personally know to exist, and they aren't as bright as blue stars. Blue stars are often-times (not always) smaller than our own sun, and yet they burn brighter. They also have a shorter lifespan. Red giants are in the last phases of their life, and expand, but are often dimmer than our own sun.

Not necessarily. The brightness of a star depends on its temperature, distance, and size. Some of the brightest stars in the sky are indeed large, such as Betelgeuse and Rigel, but there are smaller stars that appear brighter due to their proximity to Earth.
