You can beat the 5 non-flying villains in any order. If you are working left to right, the next is Ratman in the sewer under the restrooms.
Since you have to defeat all 5 villains before you can face Betty Jetty, it makes no difference whatsoever how you play them. Consistency would suggest doing them Crusher, Ratman, Sir Rebral, Speeding Spike, and Copycat i.e. farthest from Main Street to closest, or closest to farthest. Their relative locations are : Copycat-Speeding Spike (Downtown) / Sir Rebral-Ratman (City Park) / Crusher (Junkyard)
You can defeat the 5 villains in any order. Copycat and Speeding Spike are Downtown, so the next villains are Sir Rebral in City Park and Ratman in the sewer under the restrooms.
The pay phone will ring when you have defeated the first 5 super villains (Copycat, Speeding Spike, Sir Rebral, Ratman, and Crusher). Answer the phone and you get the power to fly! Then you can defeat Betty Jetty.

(1) It's right by where Sir Rebral is and you can find ratman in the bathrooms and if you mean't sewer it is in the subway and speeding spike is there.
There are 6 escaped villains to recapture. The first 5 are Copycat, Speeding Spike, Sir Rebral, Ratman, and Crusher. Once you have captured them, you receive your super flying power to chase the 6th, Betty Jetty.

The restrooms are at City Park. Use the rock to help you beat Sir Rebral, then go into the sewer through either of the restrooms, to battle Ratman.
You can play the 5 villains in any order, since you are transported back to the prison as you finish each one. The order in which you meet them is Copycat, Speeding Spike (Downtown), Sir Rebral, Ratman (under the restrooms) and Crusher. If you have trouble using the rock, Sir Rebral can be time-consuming. The same goes for Ratman in getting past the rats. But Crusher is definitely the toughest until you get his timing figured out. (see the related question)
