Just because they have "nearly" the same moves doesn't mean they're klones. A clone is defined to be "genetically" alike in every way to another character. Mileena is an example (and the only one), as she is a clone of Kitana, though she went wrong (with the whole grotesque part). As for the others:
NOTE: Some may include spoilers.
Ashrah: Has "some" of Kung Lao's moves, but is like no other kharacter, because she is, ironically, a demon trying to achieve purity.
Kobra: Has the fighting styles of Cage & Sonya, looks a tad like Sonya, but that's it. SPOILER: Kobra is with the Black Dragon, Sonya's enemies.
Havik: Havik may have the Deadly Alliance's styles, but that's all so far. Havik is out to stop Hotaru from bringing Order to the realms by causing Chaos.
Darrius: Thought to be Jax or Cyrax, he has an appearance like the two, but that's all. I believe Darrius is with Havik trying to cause Chaos.
Kira: Many think she's a cross between Sonya & Kano, but she's friggin fast & looks nothing like either of them.

I'm not talking about replacements in the storyline, I mean like, moves, styles, and other... ah, interesting to know Darrius could be evil
