All executors have the right to see the will, they cannot execute it if they do not have access to it.
Executors do not get the money, it goes to the estate. The executors distribute the estate per the will or laws of intestacy.
A will can be changed by the testator at any time. They do not need the signature of anyone named in the will to do so. They just have to meet the requirements for their jurisdiction.
Executors don't appoint executors. The court appoints them.
My husband and I are executors of a will and want to cancel this.
If the will has been entered into probate, yes. You simply need to go to the clerks office and make a request for a copy.
Generally, if two executors are named in the will and then appointed by the court as co-executors they must act together unless the will provides that either can act alone.
When co-executors cannot agree then they each need to have their own attorney (or solicitor) and then allow the attorneys to complete the proceedings. Generally, an attorney will not allow the client to impede the process unnecessarily. Generally, the attorneys will be paid by the estate so it benefits the estate for the co-executors to act reasonably and responsibly to preserve the assets that will eventually pass to the beneficiaries.
The executors that are appointed by the court. The court will issue a letter of authority to the appropriate executor(s).
