Hi, I have extracted street data from OpenStreetMap and structured the data street by street. Is there any help on how I can write a simple routing algorithm based on the extracted data to generate turn-by-turn instructions if a user chooses one street as the starting point and then another street as the destination?

There are ready-made algortihms out there on GitHub that do what you want - check out OSRM or GraphHopper. These are sophisticated routing engines where a lot of work has gone not into making them fast but also making the instructions good - which is more difficult than you might expect! Even if you decide to write your own routing engine for educational purposes, it might make sense to have a look at how these programs generate turn instructions.
