I'm assuming one of the four chargers was the stock Samsung wall charger. If even that one is not working, you may need to re-boot (restart) the phone for charging to work. I don't know if you'll be able to re-boot it with the battery that low. If not, it looks like your only option would be to buy a new battery with its own charger, charge it up, then put it in the phone and go from there.
