"Actually they were together for 3 years without any accidents. It all happened after i took them out to clean their half a room cage throughoutly and then put them back in the cage once i finished cleaning. I dont think they were lacking space, since they had a bathtub, a tree with thick branches pointing out at 2 heat bulbs, an 4 caves in a artificial big rock. But i guess that mistake was a first..."

You still don't understand their husbandry needs. Five ball pythons and only four hides? Also, your set-up (no matter how big) sounds arboreal. These are terrestrial snakes. Yes, they will bask on a branch but they prefer low, dark, and tight spaces.
No matter how big the set up you have they still need to be housed separately. Your males will spar, your females (if not of adequate size) can become egg bound if they become gravid.
Really, you need to invest in either individual tanks or a rack system. Keep one of the snakes in your big enclosure if you want a display animal. Put the rest into a rack and you will notice a difference in their behavior and eating habits.
"Actually they were together for 3 years without any accidents."
This is the same argument that is used when advocates of mixed species tanks debate. Just because three years went by without any "accidents" doesn't mean it is okay. You should consider yourself lucky that you were able to pull off a three year stint with only one accident. Fact is, proper husbandry techniques would have avoided this altogether. Saying that you went three years without an accident and then decidiing to change is a lot like using heating elements (bulbs, heat tapes, etc.) without a thermostat because "no one's been burned yet." It make take time but it will happen.
