The Octopus is a marine animal. It must stay in water in order to survive. Therefore, their food and their ability to eat is constant. Several resources state that the octopus likes crabs. With eight arms, they are able to catch anything that is swimming by them. With larger sea animals, the Octopus has the ability to stun the animals with his sharp horn. It is also capable of holding the victim underwater until it drowns, or can be eaten alive.

It depends on the species. The Giant Pacific Octopus can indeed live for five years but others live only about six months.

Octopuses only reproduce once. Males die no more than a few months after mating. The female dies once the eggs she's been guarding hatch. Although they stop eating after mating it is an endocrine secretion from the optic gland that kills them.

Yes. They grow legs and wander around looking for jellyfish to kick.

Female Octopus does eat their arms, not in a stressful situation, but while taking care of the unhatched eggs. It does so only for sustenance.

The female Octopus does not hunt during the roughly one-month period while she is taking care of the unhatched eggs. This is the time she may ingest some of her own arms. While the eggs hatch the mother is too weak to defend herself from predators like cod, and it often succumbs to the attacks.
