You got 4 right

Correct: Abbatoir, Bane, Mekros, Tally Man

Almost: Cardinal Sin (is good but not major); Clayface (not Karlo); Jigsaw (not canon)

Incorrect: Amygdala, Bird (not a major one; and that goes for Trogg and Zombie), LeHah and Nicholas Scratch (as Azrael), Cypher (wasn't Batman yet), Lilhy (as Azrael), Nekros (who is it??) and Tim Drake (not villain).

Hint: Just take a look to the covers of some of the Knightfall & Knightquest storylines.
