#12 has potential
#1 and #9 are funny, but need work
#4 is actually pretty good as it is
The rest are pretty boring.
Your problem is that you go off on these huge narratives which try to tell a complicated story. Your stories are usually interesting, but they're more than you can really accomplish with the art and format limitations on this site. What you end up with is long rambling set-up for a relatively small number of jokes.
What you really need is comicbookcreator.com. Or just to draw these things out.
If you must try these long stories, at least try to put a joke in every comic to keep it from getting boring and annoying the reader. You can further a plot and still keep the funny flowing, you know.
