Mystery/Apple snails like their water too alkaline (around pH8) for most species of peacefull aquarium fish. If you must mix them with fish you will have to experiment. One snail needs around 2.5 gallons of water. Don't try to keep them with large cichlids cause they will be eaten. They are tropical so their water needs to be heated to around 75F. Don't keep them with goldfish either.
None. Snails use up oxygen and create poo etc. Each snail takes up the same amount of room and makes the same amount of toxins as a fish. This means the more snails you have the less fish you can have in the tank.

Snails have gils.
yes apple snails are not picky eaters they will eat fruits and vegetable's along with fish food
I used to have snails with my goldfish and they got along swimmingly!
Jellyfish, sea anemones, sponges, starfish, sea urchins, sea snails, shell fish, lobsters, crabs....
Squids doesn't have lungs, they have a structure that does the same thing as the gills do for fish, take up oxygen from the water. W/o lungs, the idea of holding their breath becomes a bit strange. The closest comparison - how long a squid can go w/o new water over its gills - I have no idea.
Yes. Snails have gills, which makes them able to breathe underwater.

Cuttlefish is not a fish! It has no vertebrae and belongs to the class cephalopoda along with octopi and squid. As molluscs, they are more closely related to slugs and snails.

No.
Pouch snails eat things under water such as algae and underwater plants.
