Yes. Most credit card companies have a hardship program. Although, not everyone qualifies.  If you qualify, banks will temporarily lower your interest rate for roughly 3-12 months to help you get back on track. Sometimes, they may lower your payment and waive fees. Your financial hardship reason must be compelling to merit the benefits. Loss of income due to unemployment/reduction of hours, medical emergency or natural disaster will like increase your chances of qualifying.

In most cases, yes. But it depends on the terms the creditor is offering. If your interest rates are above 20% and the creditor is offering rates below 10%, then yes. But keep in mind, most hardship plans are temporary. Usually between 3-12 months. Look into credit counseling for a plan to payoff your debt in 4-5 years.

Yes. It can be negotiated, but only if you are severely delinquent. Typically, once you fail to make payments for six months, creditors would be willing to settle for about 50% of what you owe. However, you would need to pay that amount today in order to settle. Also, there will be tax consequences. Whatever amount is forgiven becomes taxable income. Expect the IRS to come knocking on you door to collect. If you are current with your payment, avoid negotiation. Look into hardship plans or credit counseling instead.
