Garage Band and Audacity are free and are capable of "pumping" up the volume, but that procedure might add noise to the song.

Then there is Logic, Live, Reason, ProTools, ... .

Audacity is great for this.

You can individually adjust the volume of each song in iTunes by clicking on the song, pressing control+I, and selecting the Options tab.

Another vote for Audacity for simple sound file manipulation.
