Regarding Ancestral property share

We have an ancestral property in our village which consists of: 1) Agricultural land 2) An independent house with some land nearby. I am not very clear about the property share matters in villages (Our village is in Andhra Pradesh). Till now all the property is joint property. Now my father and my uncle are planning to separate it and register in their names. 1) My father is the elder son. He did marriage of his two younger sisters. My grandparents were alive at that time. Because of these marriages, he had to borrow some money from outside. He sold 1/2acre land to clear this debt. Now, my uncle is saying that this 1/2 acre land would come under my father's share and so he would take extra 1/2acre land from the property. Is this valid? 2) My father is settled in a different place before his marriage and all our upbringing is done here. It's my uncle who stayed in our village. All these years my uncle enjoyed the property both the house and the agricultural lands. He never gave any rupee for us for using the whole property, especially the agricultural lands. Can we ask him for the money/compensation for using our share of agricultural lands all these years? 3) My uncle has a son and a daughter, both are married. My father has two daughters and we are not yet married. My three aunts and uncle want my father to give more property to my uncle because he has a son. And knowing my father, if they ask him repeatedly he would agree. I wanted this property for our marriage expenses and my parent's retirement security as my father had to stop working some months back because of his health. As per law, as its ancestral property, both my father and uncle should get equal share in it. Can we as his daughters oppose if at all they make my father give more share in the property to my uncle or his son? 4) Coming to the house and the nearby land, everyone wanted us to give that to uncle as he is staying there for many years. But we want our share in it. Can we ask for our share in it? Do we have a right to ask for our equal share which my father would get in it?
