Of course not, but keep in mind that the children of a married woman are presumed to be those of her husband unless/until proven otherwise.
No, only the biological parents pay.
no
no because if you had a baby with another man your ex husband does not pay you with more child support because that is not his child
if you have the child. And even when he does.
I suggest that you get in touch with your State's child support agency.

no, but he needs to get it modified see links below
Unlikely. Your husband is the legal father of the child.
Only if your ex husband is PAYING the residency to look after the child.You need to provide more details, such as whether you mean that your husband lives with the children at someone else's home. In that case, he is still entitled to child support. If the children are not in their father's custody then you should take the matter back to the family court that issued the child support order and ask for a ruling.
No, child support is his responsibility only.
Generally, yes, the child is still his child. The support payments would likely stop if the new husband adopts the child, but he can't do that unless you agree to it.
yes
No. If the parents are living together the law assumes they taking care of the needs of their minor child/children (at least one would hope that is the case).
