All three calls look good to me. If GNUTERM=aqua then DISPLAY shouldn't be set 
(cf. Gnuplot manual) - that's where the errors come from - so absolutely correct.

This also is okay, this is part of my selfmade startup script (cf. below) - 
necessary if somebody wants to open two Gnuplot.apps at the same time.

Yes ok.

I expect no, I'm very very sorry, as long as I can't reproduce the problem and 
don't know why no figure window is opened. I'm currently also searching in the 
dark - my last idea was that AquaTerm.framework is not opened correctly, that's 
why putting another one into /tmp/gnuplot-i386/ (which is the path where I put 
all libs before packing Gnuplot.app). If you want to do some more tests then 
also have a look at the shell script

  /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot

with a normal text editor (this is the startup script for gnuplot resp. 
Gnuplot.app if you call it from command line - like we did above). Maybe (but 
this also is just an idea and nothing more) it has to do with 10.4.11?! I 
personally am working on a 10.4.9 machine but won't upgrade to a newer version.

Finally, I somewhen already had an AquaTerm discussion at OctaveForge - but this 
was a bit different, here is the link where you can read all about it, maybe you 
get some more ideas about what to try

Let me know if I can help somehow
