Ancestral-Residential ; Ancestral- Agricultural ; Fathers Acquired Property

1.My Grandfather was allotted 25% of a dwelling residential unit, as compensation for his property lost in Pakistan during Partition, and thereby classified as 'Ancestral ' property. Is this interpretation correct ? The balance 75% of the dwelling unit was occupied by 3 other persons, from whom my grandfather purchased the remaining 75%. The whole 100% of the property is an indivisible single dwelling unit. 2. Question is : Is the Entire 100% of the Property as " Ancestral " or not ? 3. Grandfather was also allotted 9 acres of Agricultural land in lieu of his land in Pakistan , lost due to Partition. Is this Agricultural Land also to be treated as Ancestral ? 4. The Grandfather in 1984 ( & Grand Mother in 86) WILLED these properties to his 2 Sons, but nothing to his 7 daughters. What are the daughters rights now? The Sons did not mutate their fathers Will, & both have since died in 2007 & 2018, leaving No Will. One Son was not married and had no heirs, except his 2 surviving Sisters, other 5 having passed away, leaving their children & grand children.. 5. Please advice / guide respective legal rights of the surviving children / grand children in the Ancestral and Acquired properties of the Grand father ........ and the correct legal process to be followed to Legalize and regularize the stated properties in favor of the rightful inheritants / coparceners ,
