What is the division of share of joint property among family members

We have a small construction business registered to my uncle, we do govt contracts like roads and drains etc. we are planning to start a asphalt batching plant in the name of the company registered to my uncle(father's younger brother) and our's is a joint family staying 14 members in the same house, my father is the head of the family. my father has 3 younger brothers staying and doing business together, some properties are registered in name of my uncle's. my question is NO 1= do my father and other members who are staying with us has a equal right's in the share of the company ? NO 2= in future while dividing the properties among the family members, is that the company will also be divided each or it will only owned by my uncle ( registered in his name) ? NO 3= my uncle has more properties registered in his name compared to others, is that those properties will also be divided equally among others in the family?
