First, let me disclose that I am not an attorney in Florida, and the following observations are not advice. Because your questions are hypothetical, I'll answer them based on my understanding of the common law. Consult with a Florida attorney before refusing to comply with a court order.
1) Divulging private information
In general, a party is not required to divulge private or personal information to another just because they are asked. However, if two parties are contracting with each other, one may require the other to divulge private information. The asked party can make a choice -- divulge the information and complete the contract or walk away from the deal.
In the scenario you described, Company and Holder had a contract before commencement of litigation. It is possible that Company and Holder agreed to make certain disclosures in the event of litigation. Regardless of what the court ordered, it is possible Holder is already obligated to disclose private information to Company.
If there is no such language in the contract, then Holder is obligated to disclose only what is required to execute the contract.
2 - 3) Court orders & contempt of court
In general, there are two forms of contempt: direct and indirect. Direct contempt occurs in the presence of the judge or magistrate. If a party commits contempt of court in the judge's presence, the judge will inform the offending party of the contempt and will usually inform them of the penalty.
Indirect contempt occurs outside of the court's presence, and the party benefited by the order must file a complaint with the court and ask for relief. The court will hold a hearing attended by both parties where the benefited party will present evidence of the contempt.
Here, if the court orders Holder to complete various disclosures, and Holder fails to comply, the Company can file a motion with the court informing the court of the incomplete disclosure. You didn't ask, but if the court finds the defendant in contempt the punishment can be fines or imprisonment. Once the disobedience ends, the sanction or imprisonment ends.
If the court requires Holder to disclose information that Holder does not have and would not be expected to have (such as George Washington's blood type), then Holder should note that in the documentation. Similarly, if the court is asking Holder to disclose financial information that does not apply to the Holder (such as account numbers for CDs, and Holder never opened a CD account), then Holder should state that and not leave that portion of the form blank.
4) Default answers
As far as I know, there are few instances in the law where a null answer defaults to a certain value.
Here, a null answer would be considered a null answer -- in other words, a refusal to comply with the court's order.
