Not nearly enough information is given. If the "estate" being referred to is the 'estate' of a deceased parent(s) the siblings have only as much authority over the estate as the will of the deceased allows them. They each inherit individually what the will gives them, and if they inherit anything jointly, they cannot do anything with their joint-inheritance without BOTH being in agreement. It sounds like the questioner needs the advice of an attorney.
The will lays out the rights of the siblings. If there is no will, it will be split evenly.
Generally speaking, the rest of the siblings cannot do anything as long as the person with the life estate is alive except make sure that the person with the life estate takes care of the property.
No, a sibling will not be responsible for the debts. The estate is responsible for the debts. If the estate has no assets, the creditors will not get paid. If there are not enough assets to pay the debts, the beneficiaries will not receive anything.

It is important to consult with a legal professional familiar with the specific state's laws to understand the exact rights of adopted siblings in intestate succession.

The siblings' signatures are not required. The executor acts on behalf the estate. They have the power to transfer title, though they may require court approval.
You need to consult with an attorney who can review the title and how it was created. If the sibling was unmarried and without children their interest may pass to you. However, you may need to probate their estate. If there is a surviving spouse or children of the deceased sibling the situation becomes more complicated. The attorney can advise you of your options under your state laws.
Yes, the executor of the estate can make decisions such as this. it is usually best to talk it through if you are on good terms with your sibling.
The executor of an estate has no power while the individual is still living. If they have been appointed as conservator of the person, they may move them.
The person making the payments can make a claim against the estate. It may result in the non-paying sibling getting a greatly reduced share. It may even force the sale of the property, and the paying sibling can purchase it at Fair Market Value.
* The Will will go into probate first. If a sibling chooses to live in the house then they would have to buy the house from the other siblings and if this is not possible then the house will be sold and monies put into the total Estate.
