Which of these RAM chips can I use, to be compatible?
None of those sticks will work in the new system.
All three sticks you have are "PC3" or DDR3 sticks. The stick in his new system is PC4 - DDR4.
The only stick without it explicitly written on the label is the Kingston KVR16N11 which is also still DDR3.
You will not be able to physically fit any of your sticks into the DIMM slots of the new system. They are not compatible and will not work together.
