Yes and Yes

Yes. You can set up several datasources in Tomcat.

is there possibility to run 2 versions of tomcats on one system

Yes, but the two instances will need to use different ports. You will have to change the configuration of at least one tomcat, so that it does not use the default ports.

Yes. You can set up several datasources in Tomcat.
