No, it's a possible stage in the life cycle of a star.
No. A Quasar is a Black hole in center of some Galaxies. I think our Galaxy has one of them.
No, not in the slightest sense. A quasar, pulsar, and galaxy are three very different things.
Astronomers have detected a quasar in a distant galaxy.
Quite a bit more than that. A typical quasar is several times brighter than an entire galaxy that has no quasar.Quite a bit more than that.

quasar
A quasar evolves into a galaxy as it exhausts its fuel supply of supermassive black holes at its core. Once the black hole stops accreting matter and emitting large amounts of energy, the quasar phase ends, and it becomes a mature galaxy.

A quasar will have the brightest galactic centre.
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
Scientists have only recently decided that a quasar is a galaxy with a relatively new supermassive black hole that has "recently" formed. This isn't certain, by any means; only a few years ago, there was considerable debate about what, exactly, a quasar was. As small as a star, brighter than a galaxy; nothing seemed to make sense.
That must refer to a quasar - however, the claim that it is "a thousand times brighter" is somewhat doubtful. A quasar may seem brighter than it is, (a) because of gravitational lensing, and (b) because the jet is pointed towards us. In any case, a quasar is a small region in a galaxy, which is often brighter than an entire normal galaxy.
