Again, please tell (using "C-u C-x =") which ones are actually
composed, and which ones are displayed as several separate
characters.  If any of these characters are composed and the results
are displayed incorrectly, please show the last portion of "C-u C-x ="
display, where Emacs describes the composition.

Can you try some font that is known to be good at displaying Unicode,
such as Code2000 or DejaVu Sans?

FWIW, I see no problems with Emacs display of these characters on
MS-Windows: characters in each group are indeed displayed the same.
So I'm not sure what are we still discussing here, since the quality
of fonts on any given platform is hardly on-topic in the bug tracker,
and the NS font driver is not part of Emacs.
