Did Satoshi know since its publication all the applications that the blockchain would enable? Or he only thought about Bitcoin?

I doubt it. Even the phrase 'blockchain' was coined long after the Bitcoin paper was published. However, Bitcoin uses primitives like HashCash to do something that their creators never envisioned, so I don't think he would be surprised by the ideas of Bitcoin being used for things that he didn't think of.
