They supposedly are, yes.
I don't think the remaining women will be returned anytime soon though. I'm sure Hamas will return the elderly men first, if they even have anyone left to return. They didn't provide Israel with a list yesterday, which is why the fighting has resumed. It could either be because they've run out of live hostages but probably more likely because they want more than 3-for-1 for the remaining ones. They'll want to exchange them for specific prisoners, specific terrorists. So a new agreement will have to be drawn up, one that is going to be a whole lot worse for Israel.
