How did Zeus escape being swallowed by Cronus?

Cronus had swallowed each of his children as they were born, warned that one of them would overthrow him. When Zeus was due, Rhea gave birth on Crete and hid the infant in a cave, handing Cronus a stone wrapped in swaddling clothes to swallow instead. Cronus, deceived, felt no difference, and Zeus grew up safely away from him.

How did Zeus force Cronus to free his siblings?

Once grown, Zeus made Cronus disgorge the children he had swallowed, bringing them up in reverse order so that the stone he had swallowed last came out first among them. Hesiod says Zeus later fixed that stone at Delphi as a marker of what had happened, a permanent sign for mortals to see.

How did Zeus and his siblings divide the world after the Titanomachy?

Homer has Poseidon explain it directly: the three sons of Cronus cast lots, and Zeus won the wide sky and the upper air, Poseidon won the grey sea, and Hades won the murky dark below. Earth itself and Olympus remained common ground, belonging to none of the three alone, which is why Poseidon insists in the same speech that he is Zeus's equal in rank, not his subject.

Why did Zeus swallow his first wife, Metis?

Earth and starry Heaven warned Zeus that Metis was fated to bear a daughter equal to him in wisdom and then a son who would overthrow him as king of gods and men, the same pattern that had unseated Cronus and Ouranos before him. Zeus swallowed Metis whole while she was already pregnant, absorbing her cunning himself and never letting the prophesied son be born. Athena, the daughter, was born from his head some time later.

Was Zeus's rule as king of the gods ever seriously challenged after the Titanomachy?

Yes. Beyond the ten-year war against the Titans, Hesiod records a second great battle against Typhoeus, a monstrous son of Earth and Tartarus with a hundred serpent heads, born specifically to contest Zeus's kingship. Zeus defeated him with the thunderbolt after a fight that shook sea, sky, and the underworld together, and hurled him down to Tartarus, securing his rule for good.

Why does Zeus have so many children with mortal and divine women other than Hera?

The sources do not moralize about it as a flaw so much as treat it as the mechanism by which most major Greek heroes and several Olympians come to exist: Athena, Apollo, Artemis, Hermes, Dionysus, Persephone, Heracles, and Perseus are all children of Zeus by different mothers. Hera's anger at these unions and their offspring is itself one of the most repeated plot engines in Greek myth, driving stories as different as the labors of Heracles and the wanderings of Leto.
