Can any Claim be made by siblings on self acquired property

Dear Sir / Madam, In 1995, I bought a piece of land with house in my parent's name for my parents. I am an NRI. In the title deed, the property is partitioned as follows - Total land 22 cents - 11 cents in my name, 5 cents in father's name and house and 6 cents in my mother's name. Before dying, my father made a registered will stating that his 5 cents will come into my name after his death. In the title deed, it is written that I paid the entire money for the property. It is also written that my parents can only stay and use the property and it's income (like trees, etc.) till their end of life, after that the property is solely in my name. I have 2 sisters and 1 brother as well. I would like to know if there is a chance that they can make any claim on the property.
