The two poles North and South poles.
the poles of the magnet can pick the most iron fillings. Take a magnet. Roll it into a piece of paper and scrub it in the sand, and you will find all the iron fillings connected to the poles..

The one that the field strength is stronger
you would use the iron's magnestism to extract it with a magnetic tube

No, they are in heterogenous form mixed: not as atoms or molecules but only as particles they mix, you can easily separate them by physical methods: a magnet will pick out the iron particles.
Depending on how strong the magnet is the amount of paper clips it can pick up will vary. Why don't you test it for yourself?

Yes - if you can pick it up with a magnet, it has iron in it. That is why they call substances you can pick up with a magnet "ferromagnetic" - ferrous (the ferro part of ferromagnetic) is Latin meaning (roughly) "of iron", or "containing iron".
I'm not sure that it's a regularly used method, but since iron is magnetic and sulfur isn't, you could use a magnet to pick up the iron filings.
No
Yes - if you have a powerful enough magnet !
