Black holes are believed to most commonly be formed at the end of a massive star's life, when its fuel is exhausted and it no longer has the outward pressure to prevent collapse under the effects of its own gravity. They also might be formed during some particularly energetic particle collisions, perhaps those of cosmic rays, although those would be microscopic and very short-lived. They also were likely formed around the time of the big bang because of the initial conditions of the universe (so-called primordial black holes).

No. Only the most massive stars form black holes. When the sun dies it will form a white dwarf.
No, water cannot form a black hole, no matter the quantity. Black holes are only formed after the collapse of a supergiant star.
