About agriculture land gift deed in gujarat

Hello I have a Agriculture land. My father's name is not present In 7/12 and 8A documents. But in old records my grand father's name is available. After my grand father's death only my uncle's name is entered by relatives and not entered my father's name. Also a part of land is given to my cousin uncles ( 4 uncles ; out of them 2 are expired ). A half part (1/2) of land is given to me and another is given to my cousin uncles. My uncle is dead so their sons have entered their names in 7/12 and 8A. So, now 4 cousin uncles (2 are expired ) 2 cousin brother and aunty Now I want to entered my name in 7/12 and 8A. So how can I get my name in 7/12 and 8A. Can I make gift deed by aunty and 2 cousin brother? Because for sale deed permission of all members are required and it is not possible for me. So, reply a proper guidance. Thanks
