Question

are crickets, locusts and grasshoppers the same? if not how?

Answer 1

No they are not the same for-

Antennae-

Grass hoppers have short antennae and crickets and locusts have short ones

They roam in groups-

Usually grasshoppers and crickets be alone.And as you can see from the news from Rajasthan,locusts hang around in groups.

Sounds-

Grasshoppers and locusts have a row of pegs like a comb on their back legs. They scrape these pegs against the hard edges of the front wings to make sounds. Crickets produce sounds by rubbing their wings together. In order to hear these sounds, orthopterans have a tympanum (ear) on each front leg, just below the knee.
