Both are sea-dwelling, eukaryotic animals with a complex nervous system and a very intelligent brain, but that's where the similarities end. Octopi are molluscs, which makes them quite different from vertebrates such as whales. The two different phylums that these animals belong to, mollusca and chordata, have diverged very early in evolutionary history.
The first multicellular organisms evolved into different branches of animals. Some had an internal skeleton, such as the fish that would eventually evolve into amphibians, reptiles, and mammals (like whales). Others had an external skeleton, like crustaceans and insects, and others again had no skeleton at all, like octopi. That makes whales and octopi fundamentally different.
They are both aquatic mammals.

Humpback whale, sperm whale, pilot whale, Beluga, minke, blue whale and fin whale have similar adaptations.
No an octopus is not bigger than a whale
It depends on the size and type of the octopus and shark. A giant octopus can kill and eat a leopard shark, but a common octopus will be a prey of a tiger shark. Blue ringed octopus have deadly venom enough to kill a full-grown whale shark.
