Challange the will executed by your deceased father, otherwise you have no claim, interest, right or title in his self acquired property 

Yes, your father had every right to transfer,Sell,gift or bequeath his self acquired property to anyone as per his wish,you have no right ,title or interest over his property.

Sir the will is properly drafted & registered in sub registrar office, and 2 witnesses signed it. On what basis can i challenge it sir?. If i challenge it, can i get a favorable judgement from court of law

Yes, it is to be challanged on the ground of state of mind at the time of teatator (your father) when it was executed and registered, undue pressure, threat, allurment induced upon the testator.  

Judgement shall depend upon evidences produced by parties, which cannot be predicted at this stage.

Since a will is made by the onwer of the house i.e your father to the name of your brother, much cannot be done by you with the fact that you are residing there for no matter what period of time. But yes you can definitely challenge the Will of your father.

Once the Will is challenged, title of the property will be disputed and hence you can enjoy staying in the property for a longer period of time. In mean while get in touch with a advocate and try to prove the will void. Try to prove that the will was made without the true knowledge of your father and that your brother have induces your father to make the will in favour of his name which your father didnot actually intented to do.

 I have one sister too,  if i proved the will is void, can i have sole right on that property. Bcos its in my fathers name. If i prove the will is void, does my brother & sister has a legal share in it.?

One of my friend (he is not an advocate) suggest me to go for compromise with my brother instead of going to court. Will it works sir?

Is there any 

All the siblings of deceased father has equal right when will is declare void.

It is a perfect advise to settle the case amicably.

Why you are so insistent in depriving the disabled brother of his legacy?
