It's almost like you haven't read the multiple comments explaining what "terminal" means.

It simply means "not instrumental". It has nothing to do with the degree of importance assigned relative to other goals, except in that, obviously, instrumental goals deriving from terminal goal X are always less important than X itself. If your utility function is U = A + B then A and B can be sensibly described as terminal, and the fact that A is terminal does not mean you'd destroy all B just to have A.

Yes, "terminal" means final. Terminal goals are final in that your interest in them derives not from any argument but from axiom (ie. built-in behaviours). This doesn't mean you can't have more than one.
