Regarding an offender's filing of an appeal of the sentence if an appeal is filed, the prosecutor will provide the following information:
A brief explanation of the appellate process and possible disposition of the case.
Whether the defendant has been released on bail or recognizance pending the outcome of the appeal.
Check with a lawyer in your locale to discuss more of the details.
Good luck to you.

Although I do not practice in AL, if your friend wants to be released on bond pending appeal, he will likely have to make a motion to the judge. In WI (and many other states), you are not automatically released pending appeal; and you may have to make a strong showing of success on appeal before you are released.
Your friend should consult with a local, experienced appellate attorney; and the sooner your friend does so, the better. In many states, there are appeal deadlines that begin to run the day of sentencing; and those deadlines may come up quickly.
Good luck to both of you!
