Real answer : only one (Hera) the Greeks only allowed one marriage, but he had an affair with all of the others.
Actually Zeus' first wife was Metis (Athena's mother). Metis was the first goddess of wisdom, well actually she was a Titan. Zeus ate her in order to stop her from having a son (a prophecy said Metis' son would overthrow him).
Zeus' second wife was Hera (goddess of marriage and women), his sister.
Themis is also said to be a wife of Zeus between the first, Metis and Hera. The reason he is credited with so many wives and loves is because as worship of the Greek gods spread the chief god of a town or people was made into one god, while his wife or consort was said to be a lover of Zeus - and so why Zeus had so many lovers and children.
The number really depends on the tradition and stories you are folowing and if you are counting human and godly wives/children. There were literally hundreds of children. See related links below for more info.:
i think 5, Dionysus, Ares, Appolo, Perseus, and Hercules
If you include those 5 he had 117 children 112 of them being demigods
Hera had two sons with her husband, Zeus: Ares (God of War), and Hephaestus (god of fire and the forge).
She also bore him a daughter: Hebe (goddess of youth). Some sources claim Eris (discord) was also one of her children -- but it's not certain. Apparently Eileithyīa (goddess of childbirth) was also Hera's daughter. See the links below.
Zeus had 5 other brothers and sisters: Hestia, Demeter, Hera, Poseidon and Hades.
Poseidon the Greek god had 8,902 children due to the fact that he had 123 wives.
i think 4 kids.

None, just brothers
Athena, the Greek Goddess of Wisdom, did not have siblings. She was the only child of Metis (Zeus's first wife) and Zeus. However, she did have lots of half-brothers and half-sisters, due to Zeus's many children. Some half-brothers and half-sisters include:Ares, Hephaestus, Apollo, Hermes, Artemis, Dionysus, Hercules, Perseus, the Muses, and Helen.Did that help? :)
Two brothers; Poseidon, and Zeus. Three sisters; Hestia, Demeter, and Hera.
Demeter has three brothers, Zeus, Hades, and Poseidon, and two sisters in Hera and Hestia.
Yes; Persephone had many half brothers and half sisters, from her mother Demeter and father Zeus.
three sister, two brothers
Hercules didn't have a brother or a sister but because he was the son of Zeus, he had many half brothers and sisters including Apollo,Artemis,Athena,Persephone and many more( they were all offsprings of Zeus)
Since her father was Zeus, there are many step - brothers and step - sisters of Athena. She didn't have any real siblings, though.
In Greek mythology, Zeus was the king of the Greek gods and had many relatives, including his brothers and sisters Demeter, Poseidon, Hades, and Hestia. Zeus had numerous offspring who were also gods/goddesses, including Persephone, Ares, Athena, Hermes, and Artemis. There were also half-human offspring's like Heracles.
