Answer 1

flat. its a Eb because that what it says on the darn i cant think of what its called but it's flat. good luck=).

Answer 2

not flat...

Answer 3

It is left natural, not flat, because that is what the accidental marks it as in the notes previous, but in the same measure.  This should explain why:

" In piano, when an accidental precedes a note, it tells the pianist to play a different note from the original. When an accidental appears in a measure, every note that is the same as the note being changed is changed the same way. In a key signature, accidentals retain their effects for the entire piece (unless a natural has been used to cancel it)."- http://en.wikibooks.org/wiki/Piano/Accid...

In the piece you showed, the natural cancels out the normal flat listed in the key signature.
