This is actually a really good chart. I think the characters and quotes you chose line up pretty well. It's really hard to file some complex characters under a neat little category correctly, but I think you pretty much nailed them.
I only disagree with the Neutral Evil selection.. Xenomorphs are driven by instinct, and even the xenomorph queen, while somewhat vindictive, was going after the threat that just killed her offspring. The Alien xenomorphs are pretty much neutral.
Now, a better Neutral Evil is SkyNet, at least as far as it relates to humans.
Xenomorphs are definitely neutral evil. You said yourself that they are driven by instinct, and their instinct is to kill anything that moves. The definition of a neutral evil character is someone who does whatever it takes to survive, regardless of the rules or whoever/whatever gets in their way. They are out for number 1, themselves. This is evidenced in the movie Alien Resurrection where 2 xenomorphs kill one of their own kind and spill his acid blood on the floor so they could escape their prison. There certainly are better examples of neutral evil out there, but xenomorphs do fit the category.
You described a neutral evil character like so: "Someone who does whatever it takes to survive, regardless of the rules or whoever/whatever gets in their way." That is the exact definition of a neutral character. The alien killing one of their own kind to escape their prison? There are plenty of animals who would and do kill their own in order to survive.
But per the rules, animals can't be anything but true neutral. In order to have an alignment other than true neutral, a being must have the capacity to understand moral action. A xenomorph is not sapient, and therefore is incapable of moral choices.
