I have a few hibiscus plants. There are kept in a sunny place. Two of them in 24" pots and three are kept as bonsai, all of them are flowering now and get sun until mid day. The temperature reaches 40 to 45 degree by afternoon. They flower moderately well, but the size of the flowers are very small and the quality of the flower is also not very good. Color is okay. What should I do to improve the size and quality of the flowers?

I'm not sure what kind of hibiscus you have. They come in two general types: tropicals and hardy. The hardy kinds are best grown directly in the ground and grow very fast when the weather gets extremely warm. The tropicals are not hardy in the north, but make good pot plants. As long as the temperatures are warm and the plants are getting fed and watered appropriately, they should be fine. You can't change bloom size since that varies by variety.
