Sounds like the port and the charger plug aren't making good connections. I would assume certain wires are for charging and others are for data. Look at the port in the bottom of your phone. You should see a plastic piece with 5 gold wires/prongs made into it (you can see them one either side of the plastic piece). Maybe one of yours came out or got bent. I would think it's the phone and not the chargers since you so many of them are not working.
