Through the courts; you will have to prove you're not the father.
Are you marrying the father?

Probably not, given that the new marriage does not terminate the child's father's legal responsibility to support the child.
Yes, but depending on the age of your child, you might get arrested.
An obligor who fails to pay child support pursuant to an order can be put in jail.
If you have gone to family court to get an order for child support you will. Don't wait for the father to volunteer to give you money. Get it in writing through the courts and if he doesn't pay he can be arrested.
$50 at the most
yes
If you do not live with the child or directly support them you do.
If the father is on the birth certificate you will still get all your incomes. The only way this could change for you is if the father had full custody or lived in the home.
You need to contact your local child support office/agency (or an attorney well versed in international child support arrangements) and they will initiate the process. They know all the ins and outs of getting support ordered. You may have to go through a paternity test if he requests one.
im pretty sure they can but the mother is probably most responsible for the child You might have to go to court unless he pays volentarily.
