Acting as Executor for Last Will and Testament?

My dad just passed. I am executor of a simple will dividing everything (only money) between 5 siblings. $75,000 will be disbursed equally from his annuity by that company. The remaining $25,000 is in a cash bank account. I have signing power on those accounts. Can I just put that money in my account and write a check to my siblings?
