Property Division

Hi, I would like to thank all the people who can show some light on this matter. Family info: 1) Father & Mother: Alive. 2) 7 Sons: ALive & Married. 3) 5 daughters: Alive & Married. Land information during the division: Land division had happened in 1995. Land A: 5.25 Acers(Irrigation land) + House with a shared Well with the neighbours Land B: 20 Acers (RainFed land) with no house. 1)The father has property(Land A, Land B) in two different locations and has divided between his 7 sons. 2)youngest two sons have got a property in one location(Land A) and the remaining elder five sons have got in another location(Land B). 3)After the partition the 5 elder brothers decided that the land will be divide into 6 parts( 5 parts for sons and one part for the parents till they are alive). 4)Upon division the 5 sons started living in the rainfed land and with time took electricity connection and dug a well to make the rainfed land into irrigation land and decided that the land kept for parents will be supplied water on the expense of 5 sons as the parents leave with the two younger sons. Extra info: 1) Father had divided the property between his 7 sons but the land is still in the fathers name. 2) All the Daughters have no objection for land division between the sons. 3) 5 sons leaving in location B have been paying the electricity bill for the land since 1996 after the division and nothing has been claimed from the parents part of land. Every thing which grew was kept by the parents only. 4) The land was divided in such a way that 2 sons who have got less land will get the house and the elder 5 sons will get extra land but no house. Questions: 1) Will the property still be divided equally between the 7 sons after the death of the parents in both the location? 2) In case the property gets divided between 7 sons. Can the 5 brothers claim a compensation for the expenditures done on the Rain fed land to make it irrigation land? Kindly excuse in case of any mistakes in framing the questions or explaining anything.
