Question

What is the altitude of the Polaris for these cities?

Answer 1

The altitude of Polaris (the North Star) is always within about
2/3 of a degree of the latitude of the place where you're standing
when you see it.

Look up the latitude of each place on your list.  That angle will be
the altitude of Polaris as seen from that place.

Adelaide, Australia, being in the southern hemisphere, can't see
Polaris at all.
