If you do an image search there are a ton of alignment charts on this show already. There isn't a strict consensus on it. Partly because it's not a fixed point. The morality of most of the characters has steadily eroded over the seasons, so depending on what episodes you have in mind you might get a different answer.
Also there's not a huge distinction between most of the characters, really. Even characters like Charlie that can seem almost benign at times prove time and time again that they're as bad as the rest. Most of them occupy the grey area between Neutral and Evil and between Neutral and Chaotic, depending on their mood for the sake of that episode.

If I had to categorize the main cast:
Dee and Mac are Neutral.
Dennis is Neutral Evil.
Charlie is Chaotic Neutral.
Frank is Chaotic Evil.

But there are counterexamples for each of them. Some of them can switch ideals on a dime once they get a new whim in their head. At the end of the day they're comedy creations rather than consistent human beings.
