Welcome to Discuss Dramatica!
I may be wrong, but I don't think most writers use the "28 Magic Scenes" from the theory book. Signposts and PSR (Plot Sequence Report) tend to get used a lot more.
For a brilliant approach representing the most up-to-date thinking (consider the theory book was published many years ago), see this post:
Jim describes how to adjust the number of scenes by going into more or less detail for different throughlines using the Plot Sequence Report.
For a similar approach with more detail, you can consult the book Dramatica For Screenwriters (Chapters 18 and 19, but the whole book is worth reading through several times).
Finally, I wouldn't worry about what each character in a scene should illustrate. If you've assigned elements to the characters (Archetypes or Complex Characters), feel free to have whichever elements come out that seem to work in the scene. Otherwise, just do it by feel.
To me, the concept that each scene contains an Activity, an Attitude, a Situation, and a Manner of Thinking -- all operating as a Dramatic circuit -- is the most powerful advice Dramatica offers at the scene level. A bit more detail can be found by clicking the link from this quote (but don't concern yourself with the rest of the thread, it quickly gets crazy):
