My Father has two properties, self acquired as well as inherited from grandfather but denies share.

Background info:- I am 22 year old male employed, my younger brother(19 year old) is also earning but he is not graduated. However my mother is a teacher in a private school. My father is unemployed legally. he don't want to work and hates all three of us. Problem:- My parents have been living together for almost 20 years but after a certain incident my father's brother took him away from us. The incident happened when my father was beating my mother and i intervened to save her in which me and my father both got hurt. After that he is falsely claiming that i hit him, however my mother has been suffering since marriage but for society's and her job's sake she never filed a complaint. After the incident , my father has been doing a lot of things to make us suffer and get back in the house but me and my brother decided not to let him due to his doings with my mother. He used to took all my mother's money and do businesses which got failed eventually and he lost money as loan lender as well which legally we don't have any proof for. Now one day he broke into the house and took all my mother's gold from locker when no one was at home (don't have proof for this but there was no sign of forced entry in the house or locker , so howcome someone stole and nothing suspicious happened). At this moment he is threatening to sell the house (self acquired as it is on his name) and family shop (which was on my grandfather's name and now is shared by my father and my uncles).I tried to gather evidence but they are very smart. Questions:- 1. Can my mother get a share in house? 2. Can me and my brother get share in house or shop? 3. What if my father sells both properties and we don't get anything, can i or my mother do something? 4. What if we file a case, and he is restricted to not sell shop and house ? 5. Is there any way that i can ask him to pay for my higher studies or my brother's studies? 6. Can my mother get alimony? - i don't think so 7. Is there a way to make him atone for his sins and all the suffering my mother has gone through?
