I think they are no longer as mysterious as when they were discovered. At that time, it seemed incredible that what was apparently a small region within remote galaxies should be able to emit more energy than an entire galaxy. It is now known that quasars are related to supermassive black holes, and their energy output is related to matter falling into the black hole. Of course, there are still some mysteries - for example, it isn't known yet how such huge black holes were able to form in a relatively short time. And even if you know what they are, some things are still astounding - such as their high energy output, or the jets of gas that extend hundreds of thousands of light-years into space.
Quasars do not have galaxies in them, quasars are at the hearts of galaxies. All quasars are located in galaxies, as a quasar involves massive amounts of material falling into a supermassiv black hole. Neither of these can be found outside of a galaxy.
No. Quasars are at the centers of distant galaxies.

A quasar is not a galaxy. A quasar is an intense energy source associated with a supermassive black hole that is actively feeding. All quasars are located at the centers of galaxies.
Quasars are related to supermassive black holes in the center of galaxies.
Yes, quasars are galaxies where the central black hole is turned on and consuming material.

Sure; please note that black holes are among the brightest objects in the Universe. For more details, do some reading about quasars. Briefly, some quasars shine as bright as a hundred galaxies - and a quasar is a black hole.
