Pretty sure it's meant to be "ally." I've heard from some that it means "asexual," and from others that asexual is just covered by the "Q," since technically everything but hetero falls under "queer."

Depends on the definition you follow. An asexual attracted to the opposite gender would likely be classified under "hetero." But one attracted to nothing would probably just be a person with no attraction, lacking a category. Just like atheist isn't a religion.

Cis is basically a prefix that has been taken as a word and is used to refer to someone who identifies as their actual sex as their gender, and is also heterosexual. 
That picture is due to the droids being called the CIS in Star Wars.

And because of Tumblr, it's been the butt of a billion hilarious internet jokes.
