Navigating EPF Rules: Does Family Ties Affect Provident Fund Exemption for Proprietorships?

Please clear my doubt as follows:

An individual runs a proprietorship concern in which he appoints 5 or 10 employees, and so it doesn't come under PF applicable establishment. Suppose it seems that he is also a partner of another establishment which enrolls more than 40 or 50 employees and is registered under EPF. Then my question is whether it is compulsory for him to make his proprietorship concern also un-exempted for EPF?

What will be your answer in the case where the sole proprietor is a partner in the firm that is run by his father, son, or any other close relative to him - Will his proprietorship then be exempted for EPF, since it is a separate entity, or will it be coverable under EPF due to the fact that both concerns belong to the same group/family?

Guys, please help me because I need your answer in order to solve the problem I am facing with my boss. Initially, my duty was only in the accounts department. Now, since there is no EPF consultant, my boss is ordering me to go for PF inspection and I have to answer the queries required by them!

There is no connection between these firms for applicability for PF, so the first organization (5-10 employees) will remain exempted, and the other organization (40-50 employees) should be covered under the PF Act.
