A teacher told me that electron don’t even really ‘spin’ the way we understand spin. But somehow they can have angular momentum. And what exactly is the concept of half spin?

The “spin” of the electron has about the same relationship to the angular momentum as the “flavour” and “colour” of the quark has to the appropriate macro-world meanings of the word. They are just the convenient terms to describe the quantum properties of the elementary particles.
