For some you are quite close, but for others you are somewhat off

Technoir: This is more of a phonetic pun, you say it as "Tek-no-war" -> Technowar. That makes more sense since the planet is a warzone. Hardly anybody gets this.
Scraparap: Junk equals scrap. It just sounds good.
Marbelara: This one's two-fold. You got the marble structures right, but from space, Marbelara looks like a marble! You really need to play the game in order to get it.
Dreempipes: it's a fuel refinary, hence the pipes. In a bit of a joke, the enemy turtles sleep when not in fuel/water! Also, the music has a calm sleepy evening setting.
Pezrock: Come on, any of you remember PEZ? All the bricks are shaped like PEZ candy treats. PEZ Rox! :P
Crysilis: Crystals, although you did make a good point with the gold, as most crystals were gold-colored.
