No, Hestia did not have any demigod children, she was a virgin goddess.
Hera's children had diverse "powers". She being the goddess of family and marriage, she wouldn't have bastard children, and her only children are, therefore, also children of Zeus, thus being Gods. Hera's children were: Ares, Enyo, Hebe, Eilethya, Hephaestus, and Eris. Ares was the God of war, Hephaestus, was, according to Wikipedia, the god of blacksmiths, metallurgy, fire, volcanoes, technology, among others. Eris was the goddess of discord. As you can see by these examples, Hera's children all had different specialities and different powers, and therefore, we cannot say Hera's children had a certain "kind of power". Either way, if you are asking about the Percy-Jackson-demigod-kind-of-power, Hera didn't have demigod children because of the reasons listed above.

In Greek mythology, there were twelve major gods, known as the Olympians. Zeus was the king of the gods, as well as the god of lightning and thunder. Hera was the goddess of marriage and family. In relation to Zeus, Hera was his wife. But in Greek mythology, Zeus has been known to be very unfaithful to Hera, and has sired many demigod (half god, half human) children. One of his most famous children is Heracles (The Greek name of Hercules. Heracles name was changed to Hercules after the Romans took over Greece and adopted their mythology.). Being the goddess of marriage, Hera was always very angry with Zeus for being unfaithful to her, and she has a history of bringing her wrath upon Zeus' demigod children and his many lovers.
