Why do planetary bodies rotates around axis. Which force is causing this rotation and why. Also are the stars rotating as well and do planets orbit them because they are rotating or is there some other reason.

The force is called ‘conserved angular momentum’ and its a leftover force from when the planets first formed from a huge cloud of gas and dust. The cloud was spinning already and so that momentum carried over into the planets.
Stars are all spinning for the same reason planets do. Planets orbit them because they formed from the same gas/dust cloud the star did.
