What is the ruling on listening to Western songs, and what is the ruling on singing them if they do not contain words of disbelief? Do words like "prayer" or "sin" depend on intention? And what is the ruling on one who says "I feel like I am in Paradise" or likens this world to it?

Listening to music is generally forbidden, and the prohibition is emphasized if it is accompanied by unlawful lyrics. As for the saying "I feel like I am in Paradise," intending comfort and a good state, there is no harm in it. Likewise, likening this world to Paradise, as an exaggeration to express approval of a worldly matter, does not appear to have any prohibition.
