Karina -

I must admit I am a little lost as well, and I've been doing amateur astronomy for a while now.

The brightest star in tonight's sky - well, since you said "tonight" I assume you are not referring to the Sun. And since you said "star" I assume you are not referring to Venus or Jupiter. So I would say that the brightest star tonight is the same as the brightest star just about any night - and that is Sirius. It does not rise until just before sunrise.

The bigger the star's dot is ... You may be referring to a chart of some kind, that shows stars as different sized dots on the paper. If so, I would guess that the size of the dot correlates with the magnitude or apparent brightness of the star. There should be a key that makes this clear. If you are referring to the appearance of actual stars in the sky, then the question makes no sense, since all stars appear to be insignificantly small points of light in virtually all telescopes.

4 of the brightest stars - Let's see - probably Sirius, Arcturus, Vega, and Rigel. Some of these are not visible until later at night or early in the morning. If you are going by a chart, you may need to use the chart for a fixed time. Early in the evening, you should be able to see Arcturus, Vega, Altair, and Deneb.

2 asterisms - well, the Big Dipper is one, and the Pleiades are up just before midnight.

The brightest star in tonight's sky is Vega. Sirius won't be up until just before dawn.
Magnitude is the answer you want.
Another asterism would be the keystone of Hercules, the Great Square of Pegasus, the teapot of Sagittarius, and the "W" of Cassiopeia.
