Imac 21.5 as a monitor
Can I connect my IMac 21.5 late 2013 version to a new imac as a second monitor? If so, what cable do I need?

If the new iMac is a 2020 model, it will not support Target Display Mode. Your best bet is to buy an external display for your new iMac and use that, it is easier, you don't need to spend a lot on cabling, and they just work. You can find solutions beginning in the $130 range depending on your needs.
