No..It is not possible to break a magnet into a piece having a single pole..The earth has two poles and in order to divide a magnet of one pole it must be of pico size(10^-12) range or smaller.
So for every typical small piece you create, it will automatically form into a dipole or with two poles..
No.
Two smaller magnets.
The magnetism of a permanent magnet is caused by the magnetic alignement of individual atoms in the crystal structure of the ferromagnetic material. You can break a magnet into thousands of pieces and each tiny piece is a magnet with north and south poles. Each piece will attract or repel any of the other pieces depending on how they are oriented to one another.
To break into small pieces is to pulverize. If the substance is broken down far enough it will become powdered.
Very unlikely, if possible.

No. What you are asking after is the elusive concept of the mono-pole, which has successfully eluded scientists for about eighty years, if not more.
A bar magnet has two poles, a north and a south. When you break a bar magnet into to pieces, you create two bar magnets, each with a north and a south pole. So the total number of poles will then be four.

You get a bunch of smaller magnets and you will still have north pole.
sort of. magnetic fields in a bar magnet always run south to north. if you break it in half, that same S-->N direction still applies. in fact if you were to break it up into smaller & small pieces you would still have that relationship. that is to say, you wouldn't have a north only piece and a south only piece.
Think of the two ples of a magnet like two sides of a coin. One cannot exist without the other.
High pressure to a "rock" will make it crumble or break in pieces. sometimes erosion will cause it to break if it is weak enough.
The polarity of a magnet does not change if the magnet is cut into pieces. Each piece has the same polarity that it had before. In particular, if you break a bar magnet in half at the midline between the two poles, you will end up with two magnets N-S and N-S. No reversal of polarity occurs.
You can break it in any direction.
If the bar is thin enough and not too short, it should be possible to bend and then break a bar of steel.
