'Family Members Certificate', 'Legal Heirs Certificate', 'Succession Certificate', and more...

My father passed away some time ago, without leaving any 'Will'. We are 4 siblings -- I am a Hindu male, single, aged 53 years, and three sisters (all married), two older and one younger to me, and my mother. I and my mother live at Hyderabad, and so does my younger sister. My eldest sister stays in Karnataka and my second elder sister in the U.S.A. My father was a retired government employee. After his passing away, we applied at the Tahsildar's office and obtained and could get a 'Family Members Certificate' from the Tahsildar's office. This certificate lists the 'Names', 'Genders' and 'Ages' of us i.e. all our family members, including myself. That is all it contains. And/but, in addition, it (this above mentioned 'Family Members Certificate') also states two things (contains two more statements). It says/states, thus :- 1. This Certificate (i.e. 'Family Members Certificate'can be used to avail/claim 'All Government Service Benefits', and 2. (this second Statement is more in the form of a 'DISCLAIMER' and states that) this Certificate (i.e. Family Members Certificate) cannot/CANNOT BE USED/AVAILED/APPLIED a.) for 'ANY LAND-RELATED MATTERS' and b.) for 'ANY COURT-RELATED MATTERS'. Now, my father has left behind 1. a house in a central location in Hyderabad city, Telangana (partly, or part of which was inherited by him, and partly, or part of which was self-acquired by him); 2. a plot on the outskirts of Hyderabad city (wholly self-acquired by him); 3. agricultural land of a few acres, located on the borders of Telangana and Karnataka states (most of which, inherited by him, a few acres, self-acquired by him). He had also left behind a few F.D.s ('Fixed Deposits'), which we have ALREADY REDEEMED/COLLECTED from the different banks -- as we were 'Nominees' of these above mentioned F.D.s in my father's name. He has NOT left behind ANY DEBT IN ANY FORM. Now, my question is what is needed, or how to go about transferring these above mentioned assets a. Urban Property (House and a Plot); b. Rural Property (primarily agricultural land), to our names (the surviving members of the family -- my mother and us, four siblings)?! What documents are required and where to obtain them to complete the transfer process ('Transfer to our Names Process'). Also, 1. what is the difference between 1. 'Family Members Certificate'; 2. 'Legal Heirs Certificate'; and 'Succession Certificate'?? and 3. which is applicable to our case, indicated in detail, here. Also, if we have to obtain a 'Succession Certificate', do we have to pay a 'Court Fee'?! I am asking this because I have read and also been told by a lawyer/advocate, that a. there is a 'Court Fees', for obtaining the 'Succession Certificate' which is levied as a 'fixed percentage' of the 'Market Value' of the total assests left behind my father. b. Also, is there a 'Upper Limit to the 'Court Fee or IS THERE NO UPPER LIMIT'?!. In my/our case, this/it is prohibitively expensive to pay.
