264 Bat-Man, Nigerian / Nollywood The Bat-Man: Let the Gods Do Their Worst (a.k.a. Bat Man Kills)

325 Cabala, Batman 1960s series

193 Baer?, Atom Man vs Superman

245 Joe Chill, Batman Begins

153 Abner Sedgewick, It's a Bird, Plane, Superman

193 isn't Baer, but you have the source right. 76 is close enough: while I haven't watched the full special, my understanding is that while a gangster, Al Molinaro's character is called Father Ling. I grabbed his image from a screen capture of the closing credits, which is usually the fastest way to find images of specific characters in that special, though Abner came from a little before the credits because it was a good pose for a collage. Everyone else is correct; list updated.
