Further to what Saswatabanerjee mentioned, your most recent posting/response still lacks clarity and details.
Funding Agreement Status
You mentioned, "We are getting funding from a UK company..." What is the stage of the funding agreement/MOU? Has it been signed and sealed? If yes, the UK entity would surely have incorporated the Indian Directors' wages, which usually include some sort of revenue/turnover-linked salary. Please check the agreement.
If no, then it all depends on what sort of funding arrangement is being worked out. Many times, the investing entity asks for a place on the Board of the Company, so what you or the Indian Directors may think on this issue may not be realistic. It has to be approved by the investing UK entity.
Head of the Company
Regarding who will be the Head of this company, every Private Limited Company's head is its Managing Director, who is decided by the Board of Directors. Since there are only two Directors, one of them will have to take up this designation and responsibilities.
As Saswatabanerjee mentioned, in reality, it is the investing entity/individual who will have a major say in this decision/selection.
