No, they are not. But at some points, they are related.
They are related to leafhoppers, spittlebugs, and thornbugs. NOT grasshoppers or crickets.
Yes. It has 6 legs, 3 body parts(head, thorax, abdomen) It is a type of hemipteran closely related to cicadas and leafhoppers.
The leafhopper is an insect that feeds on sap and leaves from different types of plants. These include grasses, sedges, flowers, vegetable, and shrubs. Certain species of leafhoppers, such as potato leafhoppers or rose leafhoppers only feed upon these specific plants.

No, cicadas are not carnivorous. Both the larvae (nymphs) and adults feed on plant sap.
Leafhoppers, and Tree Hoppers
Cicadas are in the order Homoptera, most closely related to plant lice and leafhoppers. Cicadas lay eggs in slits in twigs; annual species hatch and mature on their host trees and sing loudly during hot summer days. Periodical cicadas drop to the ground after hatching and spend anywhere from a few to 17 years as nymphs feeding on tree roots underground before maturing to adults. "Locust" is a general, colloquial term that usually refers to migratory grasshoppers of the order Orthoptera, but is sometimes applied to other insects of the order, including crickets and katydids.
Aphids, cicadas, froghoppers, leafhoppers, planthoppers, scale insects, and whiteflies are bugs which are pests to plants. A bug is a member of the hemipteran insect order whose hallmarks are five-segmented* antennae, membranous or part-hardened forewings, three-segmented** tarsi, and tissue-piercing, sap-sipping mouthparts. *It may be longer. **It may be shorter.
Leafhoppers excrete a sugary sap that is collected by meat ants, which help to preserve or be a food source. Meat ants will protect leafhoppers so that they may collect the sap, forming a mutalistic relationship. http://webecoist.com/2009/03/01/symbiotic-bird-animal-relationships/
No the horrific bug that is a cicada is infact not poisonous
That depends on how much you care about the cicadas
Apparently, only male cicadas make sounds.
