Dear yitriana;

What is Wikipedia telling you about?,  -  Have you already ask it?

Good Luck!

You could also check a textbook for the definition of aromatic, there is, as I recall a pretty simple caluclation, that involes summing the electrons.  It will come in handy for you in the future, if you have to know the aromaticity of an anion, or a cation, see here:

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

yes and yes.
the double bonds provide 6 pi electrons in pyridine, while the electrons on the nitrogen do not partake in this aromaticity. (ie this is a "basic" nitrogen. a nitrogen whose electron pairs give rise to aromaticity would be significantly less basic).
napthalene has 10 electrons as part of its aromatic system, and according to huckel's 4N+2 rule (here with n=4), it is aromatic.
