Answer 1

You have probably overcooked the jam or have not used enough pectin.  Also check the expiry date on the packaging

Answer 2

Put it back on the stove and add sugar and cook some more,  very low heat.

Answer 4

Add some apples and some lemon juice. lemon Juice is pure pectin.

Answer 6

If you followed the directions exactly that are printed on the bottle or pkg. of pectin, it should set.  Just put it back in the pot and recook until a little on a cold plate sets.  Some jams take longer than others.
