Relative to their body size, yes.
NO!
A group of octopuses is called a consortium.
Yes, but they usually do not attack humans purposely.
Theoretically yes, though maybe not from birth. Octopi possess cells known as chromatophores, which allow the octopus to change color and blend in with its environment to hide from predators. There are thousands upon thousands of color combinations available to octopi, so I imagine they can turn purple. However, I'm not quite sure if an octopus can be purple from birth.

You can't really GET big eyes unless your born with it. Of course, you can always do mini surgeries where they take out a little fat and minimizes your eyelids so that your eyes can actually appear wider and bigger.
Sharp eyes, suckers, and big lungs

Yes, octopuses have eyes. They use their eyes to see and navigate their environment by detecting light and shapes. Their eyes are well-developed and provide them with good vision to help them find food, avoid predators, and communicate with other octopuses.
They have eyes and 8 tenticles
Like most animals, octopuses do sleep at night. They, however, don't close their eyes because they have no eyelids.
Octopuses have keen eyesight. Octopuses, like other cephalopods, can distinguish the polarization of light.
