Estate not covering bequests??

[unique]

Hello
If a deceased person's estate ends up being less than the bequests in the will, how are the amounts of the bequests decided? Are all the bequests prorated including the percentages and set amounts?
Do the executors have any say in this kind of situation?

Generally specific bequests are paid out first, but if the item is no longer available then that bequest falls away. The proportions of the rest and residue then continue to apply, if there is anything left.
