If Christian Gallo was Cris Galo, I don't think under New York law there would be a violation. If Hayter and Burmaster used Cris Galo without Christian Gallo's consent, there might be a false impersonation problem.
They might be able to beat the false name thing. As to the dates of the contract being cancelled, we'd need more information to know.

New York Penal Law section 190.23, False
Personation, makes it a class B misdemeanor to misrepresent one’s
“name, date of birth or address to a police officer.”2 Penal Law section
190.25, Criminal Impersonation in the second degree, makes it a class A
misdemeanor when one (1) “impersonates another and does an act in
such assumed character with intent to obtain a benefit or to injure or
defraud another;”3 or (2) pretends to be a member of an organization
with intent to benefit or defraud; or (3) pretends to be a public servant
(or wears a badge or uniform) or pretends to be acting with the approval
of a public agency to induce another to: (i) submit to pretended
authority, (ii) solicit funds, (iii) act in reliance on that pretense.
