If demand shifts right and price increases, then the total revenue to the group of sellers increases for both elastic and inelastic supply curves. true or false?

Yes that is true because revenue= price multiply by quantity so if price increases then revenue will increase. the total revenue for sellers will be greater in elastic curves because the quantity supplied is increased by a larger amount than the increase in price and they wil earn more revenue and vice versa will inelastic supply curve.
