Albertosaurus lived between 71 and 68 million years ago. Stegosaurus lived between 155 and 150 million years ago, meaning that they died out 79 million years before Albertosaurus existed. If they had lived at the same time and in the same place, though, Albertosaurus would have hunted Stegosaurus.
Baby Stegosaurus would have made an easy meal for almost any carnivorous dinosaur, even small ones like Ornitholestes. However, Stegosaurus lived in herds and the parents would have done their best to protect the youngsters. Adult Stegosaurus had predators too, though. Carnivorous dinosaurs large enough to hunt adult Stegosaurus include Ceratosaurus, Torvosaurus, Allosaurus, Epanterias, and Saurophaganax.

Stegosaurus lived 80 million years before Triceratops evolved. They were both herbivores, so they wouldn't have been natural enemies even if they had lived at the same time. If they had lived at the same time though, they probably wouldn't have been "friends" either, because most species only form relationships of any kind with animals of their own species.
Stegosaurus fossils actually date to between 155 and 150 million years ago. Using various methods, paleontologists are able to determine the age of rocks. Then they know that fossils in those rocks are the same age as the rocks. In the case of Stegosaurus, they know the rocks are between 155 and 150 million years old, and they know the Stegosaurus fossils are the same age.
Dodo birds died out only a few hundred years ago. Thus, the plants alive when they existed were the same as those that exist now.
The same as today. They lived all across Europe.

Stegosaurus fossils come from the Morrison Formation in the western USA and date to between 155 and 150 million years ago. Some have recently been found in Portugal from the same time period, so they probably lived throughout North America and much of Europe. At that time, the area was a semi-arid subtropical plain with distinct wet and dry seasons. Near rivers, there were forests of conifers, cycads, ginkgoes, ferns, and horsetails. Further from the rivers there were open areas covered in ferns with scattered trees. It is believed that Stegosaurus preferred the drier fern fields.
