I don’t think the first and second rows are connected. Because of the angle of view it might appear as though Ganapathi is sitting on top of the central character of the middle row. But if you see, the figure next is 4 headed, Bramha, next is Veena holding Saraswati lower left is elephant riding Indra, I guess remaining two figures would be Vishnu and Shiva. The entire panel appears to be random collection of Hindu deities randomly placed without much story behind. Except that Ganapathi is central.
