His signing over his rights does not terminate his child support obligation.
That depends on state law where you live. It can vary.

There is 'Father's Rights Association of New York State' in New York. It is there to protect fathers rights in New York.
You would need to have the birth father's parental rights legally terminated. This can be done eithervoluntarily: he signs the paperwork.or involuntarily; this is difficult, and whether it is possible at all varies from state to state.
Whether adoption is required in such a case might depend on the law in that State. Adoption is ordinarily the next step.
Terminating parental rights does not mean you are no longer obligated to support the child so you still have to pay child support. Unless the child is adopted. You will have no rights to the child at all if you have your rights terminated and the court will not give them back so be sure what you are doing.
If you relinquish your rights you are not entitled to visitation.
Generally, no. Married or unmarried, the law considers the father's rights equally.

This varies from state to state. step 1 for the bio father would be to sue for paternity; if he does so, he will establish his parental rights and may be responsible for child support as well as have visitation rights, or even be able to sue for custody.
