You can apply to be appointed executor of your father's estate. The court will issue a letter of authority. You will be required to distribute the estate according to the intestacy laws of the state.
No. If your stepmother was executor of the estate, she still is the executor and entitled to those funds, not you.
Assuming the person who made the will is still alive, he/she can do another will or do a codicil to that will that changes the executor to someone else. If the person who made the will is dead, he/she cannot change the executor. Obviously.

Yes. You can notify the court that the executor has died and request that you be appointed the successor.
Petition the court to have them removed and replaced. In such cases the court is likely to appoint an attorney to serve as the executor.
