Off the top of my head, just talking about what we see onscreen:

The first time that the Kankers and the kids meet (onscreen) is in "Over Your Ed" when they crash The Ed Show. They don't really make contact with the audience, but this is the first time that the Kankers and the kids meet onscreen as a group.

As for individual onscreen interactions:

The first time we see Kevin with the Kankers is in "Dawn of the Eds," when he's captured by them and they taunt him. Jonny 2x4 and Jimmy have their first real conflict with them in "Avast Ye Eds," when the Kankers pursue Eddy's Creek Cruise, which they were passengers on. Jonny wrecked the Kankers' pirate ship their, and was subsequently forced to walk the Plank along with Jimmy.

They don't really have any face-to-face contact with any of the other kids as anything but a group, because the kids have learned by this time to scatter when the Kankers come around, so the next time that they show up and have an interaction with any of the three left on your list (Rolf, Sarah, or Nazz) is in "Ed Overboard," when Rolf actually goes to the trailer park to rescue Ed, considering it his Urban Ranger duty. (It doesn't end well for him.) They also find Sarah in "Run for your Ed," where the Kankers torture her until Sarah realizes that they want her to sell out her brother–which she gladly does.

I don't think that Nazz and the Kankers ever really have direct contact anywhere in the series. It's possible something happened during "Run for your Ed," but nothing is shown onscreen. Marie does use Eddy to hit her during "May I have this Ed?" but they never talk to each other. Even in the movie, we don't see Nazz getting captured. So I'd have to say that Nazz and the Kankers never interact.

This help?
