Though details are lacking in your question to enable a pointed answer as to the respective share of co-sharers, in the light of Muslim Law, it appears that the issue involved is enforcement of your right of share in the property, division thereof by metes and bounds and after getting independent possession, development of that slice of the property.
If any of the co-sharers declines to amicably settle your claim, the only remedy is to file a suit for partition, in the jurisdictional civil court. Such of the co-sharers, who would like to join you, in the litigation, can be co-plaintiffs. All the co-sharers, who do not join you are to be made parties to the suit, as defendants.
Depending upon the place, workload of the court and number of witnesses, the case may take 2 to 5 years to get concluded. Assistance of a competent lawyer is necessary.
