No one knows for sure how dinosaurs communicated. It is suspected though that they communicated both vocally and visually with one another.
In a rudimentary manner much the same as lower animals do today.
They did not exactly speak, but there is little doubt that they used sound to communicate.
Dinosaurs likely communicated through a combination of vocalizations, body language, and visual displays. Some dinosaurs may have used sounds and gestures to convey information such as warnings, mating calls, or territorial boundaries. Fossils and studies on modern-day animals can provide some insight into how dinosaurs may have communicated.
HA! there are no genetic mutations! DINOSAURS ARE DINOSAURS! DINOSAURS ARE DINOSAURS! no mutants

Yes, dinosaurs did communicate with each other. We know that lambeosaurines, such as Parasaurolophus, could use hollow space in their crests as resonating chambers to create sounds, which would have been used for communication. Although dinosaurs probably didn't roar like they do in movies (there is no evidence for the structures that would permit roaring), they may have hissed. Also, posturing could have been used to communicate, either threatening another dinosaur or to be submissive. Because they are extinct, anything else would be speculation.
Platypuses are not dinosaurs; nor are they related to dinosaurs.
Sharks are Sharks and dinosaurs are dinosaurs. But there were animals recognizable as Sharks living when the dinosaurs did.
Young dinosaurs would have been called hatchlings. If you are asking what evolved from dinosaurs, the only descendants of dinosaurs are the birds.
Most dinosaurs were herbivores. There was a wide variety or carnivorous dinosaurs, though, and all herbivorous dinosaurs evolved from the earliest carnivorous dinosaurs. Birds are descendants of carnivorous dinosaurs.
Dinosaurs never flew dinosaurs were land reptiles although some dinosaurs could swim
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
