Can we use 3CX cloud or on-premises key for another on-premises installation ?

Simple answer no

The only license where you can run two instances is the enterprise license used in failover setup

Unless of course you mean you'll be decommissioning the old machine then yes you can.

And is it possible to install on an exiting enterprise lisence and then move to professional?

Are you trying to run two 3cx systems at the same time using one license key ? This is not allowed as mentioned a above

If you want another 3cx system, depending on your requirements get the free license key, which you can currently upgrade to enterprise for a year, after which it automatically downgrades to standard license
