OK, while something else was running, I did played around with your problem.
While the logic I'm using is probably all wrong, it demonstrate how you can
simulate an 'unless' depending on multiple properties. In the build.xml
below, the 'test' target will *not* executes if both c1 and c2 are defined.
I repeat, the logic I'm using is all wrong, but you should get the idea.

No you cannot. OTOH, you can add a dependent target that uses <condition>
with <and>/<or>/<equals> to your licking to set your 'unless' property or
not. Cryptic, but I'm busy ;-) --DD

Subject: Multiple Properties for the "unless" Attribute
Hi!
Is it possible to specify multiple property names at once (separated by
commas) for the "unless" attribute of a <target>. (I would like to verify
the existence of more than one property at once.)
TIA for any advice!
Kind regards,
Holger
