The closest ones near our galaxy.
ALL of them, except the Milky Way and the Andromeda galaxies.
See related questions.
You can see Earth, Mars, the Moon and galaxies!
The vast distances involved means that the light we see left those galaxies a long time ago.

Yes. See related question.

They are literally "uncountable"; every time we improve the telescope, we see more and more galaxies.
Stars, star clusters, distant galaxies, galaxy clusters, nebulae, ...
Around 42 named galaxies, with 13 possible additions. See related question.
ummmm, galaxies can have galaxies in them unless they combine, also, we don't know, the universe is infinite and we have ye to see beyond our local galaxy cluster... sorry but that is an impossible question (although if the universe is infinite then nothing is quite impossible...)
There are an estimated 130 billion galaxies, and most all of them are undiscovered since we have only mapped a very tiny fraction of the whole universe. As we look further in space, we see back in time. On the outskirts of the universe, we can see galaxies with quasars, some of the first galaxies, their quasars in their centers have probably burned out by now and they are just regular galaxies, but we see them as they were billions of years ago with their quasars burning, their light is just now getting to us.
