Redevelopment of pagdi property - tenant paid by builder

1. My grandfather along with his 5 children lived in a pagdi home 2. At the time of my grandfather's death only 2 sons and their families were living with my grandfather in the said property. 3. One other son and 2 other daughters lived with their families in other homes 4. After my grandfathers death one of the two sons living with him also left with his family 5. Now my grandfathers home was occupied completely by one son, his wife and children. 6. This son sent a letter to his 2 brothers only, requesting for NOC to get the rent receipts in his sole name, however none of the brothers gave the noc. 7. After around 25 years after my grandfathers death, now the property has gone for redevelopment. 8. The builder vacated all the tenants by paying them and so the only son who was residing here has taken away the entire sum and refuses to share it with any of his siblings. 9. After a month or so of vacating this son also expired leaving behind his wife, 1 married daughter and 2 sons. Question :- 1. Can the other son who was residing along with his family at time of my grandfathers death claim share in the money given by builder? 2. Can the other siblings (legal heirs of my grandfather) / their legal heirs also claim share in the money given by builder?
