Do I need to answer a cross-claim made by two of the plaintiff's towards I & other 2 plaintiffs if there's also a settlement?

Life Insurance company filed a lawsuit against 5 of us because there was a contestation on the latest beneficiery document that changed the beneficieries. The contestation was made by the two plaintiffs that were taken off of the beneficiery document. I answered the complaint filed and so did the two plaintiffs, in the two plaintiff's answer (they have one lawyer rep both of them) there was also a cross claim against the 3 plaintiffs (including myself), but at the same time we have also reached an agreement. The lawyer will be sending it to all of us soon. Do I need to answer the cross claim? If I don't what happens? Is the cross claim only for procedure since we had already discussed agreement? How long before they send the agreement form before I need to start worrying?
