With them eaten away like that I'm not sure you will find enough left in the connector to attach to, plus when you try to solder to whats left of the pin the connector will start to melt. Molex makes right angle connectors similar to yours, as long as you got the same pin spacing you might get by using one. What plugs into it? another board or a cable, if a cable you could remove the connector and then cut the wires from the other cable one at a time and solder them to the board using the holes the damaged connector was using... what ever you do try and get a smaller soldering iron not a monster gun type.
