I wouldn't consider the first season to be 100% "canon" in relation to the 5 families. I think except for the Jersey and the Lupertazzi family, the rest are supposed to be the same as real life ones since a lot of real mobsters are mentioned throughout the series.. the Colombos are also mentioned by name.
The Lupertazzi family is instead of the Genovese or Lucchese, that much is clear.

-What's a couple?
-Hmm, more than a couple... Really I don't know the exact amount, maybe I shot him 10 times, 12 times?
-Maybe fifteen?
-Hmm, it could've been fifteen...
