I've never checked if I have any old kernels so I checked

Do I need to remove these? If so what's the best way? There seems to be several different ways.

Many thanks.

You just run an apt autoremove to remove most old kernels. PVE will still keep some old kernels so you got a fallback option in case there is a problem with a new kernel.
