If they aren't parties to the lawsuit they do not have to answer any interrogatories. If they are witnesses you can informally ask them questions. However, if they are witnesses and part of the Defendant, then you would have to formally take their deposition.
I would highly recommend you contact an attorney ASAP on this website. The Federal Rules of Civil Procedure are highly complicated and you need an attorney to help you.
Best of Luck.

I would need more information before I could provide you with a proper response. However, you would have to subpoena them. You could subpoena them for deposition and for trial.
