How would you say "those apples"?

As azok is those instead of these maybe it should be those are apples rather than they are. Although if you were pointing out apples in english you could say they are applea pointing to them as well to distinguish them from pears for instance. Maybe it is like that with the emphasis on azok? As I am not a hungarian speaker I do not know. Nem tudom.

OFF: I just wonder that we have apples and windows all over the lesson but there are no penguins, red pandas or small green robots...

why is azok not changing almák to the singular?
