If you're in the US, he'll have the same rights as any other father. But, even if you don't voluntarily add him, it's a simple matter for him to file a petition with the court to establish paternity and if he is determined (via DNA testing) to be the father, the courts will order that he be added.
A child's biological father can have his name added to a child's birth certificate regardless of whether or not the mother agrees to it. If the biological father voluntarily relinquishes his parental rights and the child is legally adopted by another man, his name can be added to the birth certificate in place of the biological father.
no, changing the birth certificate requires adoption, and can only be done if the birth father's parental rights have been terminated.
He would have all of the rights that a biological father has. If he was not the biological father, then his name should not have been put on the birth certificate in the first place, unless he adopted her and the birth certificate was changed.

Yes - the man signing the birth certificate is the child's legal father unless/until established otherwise in court.
A father has parental rights regardless of marital status most states.
the bio-father still has more rights as obvisouly he is the true father
If it's established who the biological father is, regardless what name is on the birth certificate, he will have to give up his parental rights in order for someone else to adopt the child. He can also go to court and have the name on the birth certificate changed to his.
The same if he is listed on the birth certificate. NONE
If he can prove that he is the biological father of the child, he can seek custody or visitation rights, regardless of whether or not he is on the birth certificate or paying child support. In fact, if he is the biological father he can legally have his name added to the birth certificate. However, if he has not been around for 16 years, it is unlikely that a judge will grant anything more than visitation rights, and the child is old enough to have a say in whether or not they want visits from their father.
Single fathers have no rights in any state see link below
DNA testing can be done before or after a birth certificate is signed if there is any question about who the father of a child is or if visitation rights are being contested.
