A single collapsing star can become a black hole. If by "1000000" you mean that the black hole is supposed to have a million solar masses... Well, any matter that falls into a black hole will add to its mass. It can be stars, but it can just as well be other black holes, neutron stars (i.e., dead stars in both cases), gas, dust, and even light (light won't usually add much to the mass). I don't think it is known very well how many stars are typically devoured by a black hole until it reaches that mass, since not much is known yet about how such black holes form.

Can any black hole turn into a neutron star?
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
