A nuclear reactor is an assembly of fuel elements (uranium usually), a moderator which can be ordinary water, heavy water, or graphite, and control rods. The reactor is made to reach criticality when uranium fuel will produce a steady power output as a result of nuclear fissions which release heat. The heat is used to produce steam which feeds a conventional steam turbine/generating unit.

No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
There are several types of nuclear reactors, with the most common being pressurized water reactors (PWRs) and boiling water reactors (BWRs). Other types include heavy water reactors (HWRs), gas-cooled reactors (GCRs), and fast breeder reactors (FBRs). Additionally, there are specialized reactors like research reactors and small modular reactors (SMRs). In total, there are more than a dozen distinct reactor designs used for various purposes worldwide.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
No, at least not for power reactors
Yes, stars are fusion reactors.
As of 2021, there are around 440 nuclear reactors in operation worldwide. These reactors are used for generating electricity through nuclear fission reactions. The number of reactors changes over time due to construction of new reactors and decommissioning of old ones.
Nuclear reactors use nuclear fission.
The US with 100 (I am uncertain if this is all reactors or just power reactors though, there are several small reactors operated to make medical isotopes, etc. or for research purposes of various kinds).
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
There are over 400 nuclear reactors around the world.
there are no bad things about the nuclear power reactors
