Hello,
You can take a look at the flink stateful functions playground[1] where you
can find  a handful of examples, in all the supported
SDKs, in addition for each language you will find a walkthrough that shows
how to use the individual SDK features.
Furthermore take a look at the documentations [2][3].

Generally, remote functions from different languages can be mixed, you can
deploy a Python function and a Java function
that can send messages to each other using the built-in type system[4].

Good luck,
