The two older ones worked, the three younger one didn't.

The burned / melted end of your glow plugs is not good = wear factor.
I test / save the functional ones and give them to owners in dire financial situations.
Under no circumstances will they go back in my personal vehicles.

I will WARN you, don't over tighten the 8MM glow plug nuts.
The threaded stud is directly attached to the heating element = over tightening will distort, stress, and/or break the NEW glow plug heating element.

Stop tightening at the first sign of wire terminal movement, this is an electrical connection measured in very low inch pounds of torque.

Here is more data than you need on the topic of glow plugs.
