I have no idea how reliable this is. ComicBookMovie says "Geeks WorldWide" (never heard of them) has been "spot on" lately - I certainly have my doubts - but just in case this is legit, here's who they're saying are the four primary villains...
The Riddler - Likely the main villain, who will be "a criminal mastermind in Gotham City who takes delight in incorporating riddles and puzzles into his schemes, leaving them as clues for the authorities to solve." Reeves is apparently seeking a male actor of any ethnicity between the ages of 30 and 40.
The Penguin - A "Gotham City mobster." He is a "short, obese man with a long nose, and he uses high-tech umbrellas as weapons." Reeves is apparently searching for a male actor of any ethnicity between the ages of 20 and 40.
Catwoman - A "Gotham City burglar" who "wears a tight one piece outfit and uses a bullwhip for a weapon." Reeves apparently wants an actress of any ethnicity between the ages of 20 and 30.
Firefly - A "professional arsonist known as the 'Firefly,' who attempts to burn all the places that he lacked the privilege to go as an orphan child." Reeves is apparently searching for a male actor of any ethnicity between the ages of 20 and 30.
These descriptions are so obvious and generic (the last one being particularly terrible, though the villain sounds cool) that I can't tell if it's done on purpose on the part of WB so as to not reveal anything else, or Geeks WorldWide is just that bad at reporting/click-baiting. That said, considering Reeves is officially in the casting stage, this *is* when character info/breakdowns like this would start leaking. So who knows...
