When we can expect 'the second step' to be translated into english to and are there planning for 'third step with object pascal'..!? 
Third step with object pascal ...
So you need more challenges. You should learn and improve the code of Lazarus itself and its libraries. I guarantee it is an educating experience.
Other developers will be very helpful if you show a real effort to learn the code. You will not only learn pascal but also the work-flow of a big open-source project.
In practice, take some bug tracker issues, fix them and upload patches. Ask questions if you need.
If it starts to feel too easy, there are issues like: "Please implement undo and redo for the form designer"
