>in a salary of 5000 Euros per month, how much could I save per month after my food and rent expenditures?
You'll have around 2900 after taxes, and you'll probably spend around 1500 for the normal cost of living (apartment, food, etc). However this varies a lot from person to person, for example sharing an apartment is way cheaper. Rent prices vary by location, and so on.
I'd suggest visiting Germany and seeing if it's something you'll like, the culture, the language, and so on.
