Who were the 5 main people that signed the declaration od independence?

Maine was NT one of the original thirteen colonies (it was part of Massaschusetts at the time), so no Maine people signed it ;-)

Not sure if it's what you meant, but, from wikipedia:

"On June 11, 1776, Congress appointed a "Committee of Five", consisting of John Adams of Massachusetts, Benjamin Franklin of Pennsylvania, Thomas Jefferson of Virginia, Robert R. Livingston of New York, and Roger Sherman of Connecticut, to draft a declaration."
