I'd says congrats on your new pals, but I do have to wonder what you are doing?? Not judging, just wondering...why did you get NINE female veileds? Is your plan to breed and get lots of babies?? Lots of $$, time and care. Even with no breeding you will have to contend with all of your girls developing and laying infertile clutches - Luna laid 4(!) in the last 12 months and I had over $1000 in vet bills total in that time frame.
As Josh pointed out, you will need 10 separate 2x2x4' cgaes: 9 for your girls and one for the male you plan to get. Do you have other herps? Have you kept chameleons before? (now be honest...
How old are they? You said they don't seem to get along - uhhh, were you not aware fo this before purchasing? Btw, WHERE did you get them - all from a a pet store???
I have to say, that from your photos they look older and the one hanging from the screen looks emaciated - can see all her ribs 
Hope you know what you're doing...
