I think reptiles are no longer classified under their own taxon, therefore they have to be distinguished between avian and non-avian to be able to get the technical wording correct

Are parrots in the time when dinosaurs were alive?
In the sense that birds are dinosaurs, and thus that dinosaurs are still alive, yes. However they were not alive when non-avian dinosaurs were around. Parrots did not evolve until a few million years after non-avian dinosaurs died out.
Is the Crocodile really a descendant of the dinosaur?
Crocodilians are distantly related to the dinosaurs in that they are both Archosaurs, but the former definitely are not descended from the Dinosaurs. They are both members of what is known as a ''crown group'' (the Archosauria). This refers back to a long-extinct bevy of Reptiles that includes the common ancestor of the two living archosaurs -- crocodilians and birds -- and the extinct avian and non-avian dinosaurs. In short, they are related only in that they (crocodilians and dinosaurs) both evolved from the same ancestral reptile.
Why is it hard to classify archaeopteryx?
