Is it possible to list all environment variables from a Windows' command prompt?

Something equivalent to PowerShell's gci env: (or ls env: or dir env:).

Just do:

SET

You can also do SET prefix to see all variables with names starting with prefix.

For example, if you want to read only derbydb from the environment variables, do the following: 

set derby

...and you will get the following: 

DERBY_HOME=c:\Users\amro-a\Desktop\db-derby-10.10.1.1-bin\db-derby-10.10.1.1-bin
