Yes, but she can wait up to 18 years to file for retroactive child support. see related question
No. I believe a one-night stand is something a couple can work out, but if it was a long time affair and a child came of it, then it would end in divorce.
Since your husband got the mistress pregnant this is good grounds for divorce. Your husband is entirely responsible for paying child support and this is called being responsible for your own actions. Your husband is fully to blame as he either started the affair or he could have said no to the woman. Therefore, the mistress who is pregnant has every right to keep her child. Your husband has created a great deal of pain for you or any children involved in your family; he lied and disrupted your lives and cost the most precious thing of all ... trust in each other. Most people who cheat will do it again.
If you're asking yourself whether you could have pushed your husband to have an affair with a married woman, the answer is "no." You simply do not have that power. Instead, it was a series of poor choices your husband made that most likely led to the affair. For instance, he decided to look outside the marriage for something he apparently needed. He decided to have an affair. He decided to ignore the marital vows of both your marriage, and those of the married couple's wife whom he had an affair with. So in short, don't blame yourself for your husband's behavior. He's not a child, and you are not responsible for his actions. That said, marital discord is very rarely, if ever, a single sided occurrence. Both parties are responsible for the maintenance of the marriage.
The courts will determine the husband's ability to pay support and enter an order reflecting that; so, the answer to your question in a word is, probably, no.SEE LINKS BELOW

ANSWER: Even if your husband is an affair material, that will not be his legit reason why he is having an affair. It can't be that he is not getting his needs at home, it will explain why he ask you to marry him if he will betrayed you.
No
You do not tell your husband's girlfriend's employer anything. The employer is a businessman and is not interested in the private affairs of his employees unless it interferes with their work performance. It should be your husband you are going after and if you feel the relationship is over then file for divorce. Your husband is the one that started this affair because he either provoked the affair or he could have said 'no' if she suggested having an affair with him. Put the blame where it belongs ... your husband!
No, it is not a mistake to tell the husband his wife was having an affair with your husband. However, some wives can be in denial and they may not believe their husband is cheating, but most do.
If your husband made one mistake in having an affair and has not cheated before that or after the affair then the child is part of him and also the biological mother. You have two options: #1 You can accept the child when and if he has custody of the child and make that child part of the whole family or #2 let him see his child if he wants too (he at least should pay child support) but see the child away from home. The decision will have to be discussed between you and your husband.
If the man she had the affair with wants to know if it is his child then yes, a paternity test should be done. This will tell whether the husband or the man she had the affair with is the father. If the father of the child wants to be part of his child's life then arrangements should be made for visitation rights, but, he should agree to help support his own child even if she stays with her husband. He might agree to be called 'uncle' so the child will not know that is his biological father This is a difficult situation and it will take the three of you to agree as to what will happen tin the future. It is quite possible that the man she had the affair with my not want anything to do with the child. If the wife and husband feel they can work it out in their marriage they should certainly try.
