When cooking several chicken breasts, pork chops, or steaks at once, you are only able to insert the probe into one of them and I don't suggest trying to remove the probe from one piece of meat and move it to another. Instead, you can use an Instant Read or a second probe thermometer if you want to monitor the other pieces that don't have the probe inserted. If all of your pieces of meat/fish are about the same size, they should cook at about the same time. If you are trying to cook a 1" thick pork chop and a 2" thick pork chop, at the same time, I would insert the probe into the thinner one and remove it when it is done. Then insert the probe into the thicker one and reset the grill to finish cooking.
