For me Id keep it down to a similar amount as it is done in "the aristocrats otherworldly adventure" anime. A god of creation, a god of war, a god of the earth, a god of commerce, a god of technology and invention, a god of magic and a god of the cycle of life and death.
there really is no need to have a god for every race for the main pillar gods represent all and appear if they decide to do so however the races would perceive them. as for any evil deities you could always make a similar number or even drop it down to a single one whom fell at odds with the other gods
