Yes that is possible however the married father is presumed the father until you overcome that presumption, you will need a lawyer to assist you.

Is there anything that can be done about my ex-wife lying to the judge?

I understand what you are saying however this will go nowhere, you can try to allege perjury etc the chance of a judge doing anything is 1% or less.

If the child is an adult dependent person unable to function on her own then you are liable for child support for the rest of her life.

Not much you can do here unless there is a threat, rise above their childish bantar and live your own life.

I am paying child support but I have my son half the year. Why am I paying when the time is shared 50/50?

Having another child will not help you. If you have the child 50% of the time there should be no child support paid, all things being equal.

How much child support will I have to pay?

$350 - $600. per month for one child (in my opinion, especially if she has day care costs $$$)

I just found out that I have a writ of bodily attachment issued for me for support. Is there a way it can be withdrawn/canceled?

you have to comply with the writ which most likely means you have to pay money to the sheriff listed in the writ not the clerk.
