Can you be reimbursed for funeral expenses and probate from your siblings from a sell of a estate?

These would be valid claims against the estate. It should be a debt that the estate pays. No they are not personally responsible for the debt. One of the primary reasons to open an estate is to resolve such debts. The estate has to pay off the debts. If the estate cannot do so, they distribute as best they can. If the court approves the distribution, the debts are ended.
