I wouldn't let them have anymore "play dates" now. After they have been apart for 24 hours they forget the scent of the other one and see them as a potential enemy and probably fight.
Jade will have his companions in 6 weeks and be happy, don't forget to make the split screen - this is important to ensure that the boys don't get hurt. In the mean time you can give him extra attention
I would suggest you take a look in the bedding for the lost gerbil - when one of mine went missing at 15 days old I found that he had died and was burried in the bedding. She may not have disposed of the body so it will need removing. I hope that the other 2 survive (and that you have one male and one female pup!!)
