How can the inheritance of a house be divided among the heirs, and what is the share of each of the paternal and maternal aunts who have passed away, and what is the share of the brother's children from their grandmother in this house, and on what basis is the price of the house estimated?

Your grandfather's inheritance, which is the house, is divided into eight parts: your grandmother gets one-eighth, your five paternal aunts get five-eighths (one-eighth each), and your father gets two-eighths.

If your father passed away, his children would inherit from him and would block his siblings from inheritance.

If your grandmother passed away, her daughters and her son's children (you and your siblings) would inherit from her.

Each paternal aunt has one-eighth of the house from her father, and two-thirds of her mother's one-eighth share. The paternal aunts have no inheritance from your father's share.

You and your siblings inherit your father's full share and one-third of your grandmother's one-eighth share.

The house is valued at its current market price when dividing the delayed inheritance.
