Can I install 12 c developer and keep 11g?

I want to start working with 12 c, but must keep with our 11 GR 2 production version until we have upgraded.

Can I have both versions on the same workstation?

You can install both on the same machine (I assume you mean Windows), but before that, you must remove the references v11 of the Windows system parameters (for example, PATH and CLASSPATH, etc.).  In addition, it may not be necessary to run both at the same time, unless you are really careful with these settings AND make sure to change the port numbers to not be in conflict with each other.
