Of course its possible, if they killed each other every time they saw each other in habitat they wouldn't be a particularly successful species. Given a large enough tank and the right mix of fish I'm sure multiple jars could be kept in the same size tank.
In the wild they would have enough space to get away from each other, I highly doubt the OP has a tank big enough replicate this. It would most likely not work as aro's are even more intolerant of each other than other fish and the fact that they're jardini makes it even less likely

You're right, perhaps the OP should have specified the tank size. He simply asked if it was possible, which is obviously is if you have a big enough tank...
