Can director of a pvt ltd company take personal fee?

Hi,

My friend is a director in a pvt ltd company. He is into interior design and previously did freelance constation too. After becoming a directors can he still continue with his freelancing work and take the consultation fee in his personal account? Also few of his clients are now with his private limited company that he incorporated along with 4 others. Is it okay if he takes money from those clients too. The client want to pay him personally instead of a company for their own personal reasons. All payment is through check or bank transfer.

please guide

thanks
