Question

who are the new characters introduced in scene 2 of THE diary of anee frank? and how do they seem to be adjusting to their situation?

Answer 1

I assume you mean Scene 2 of the stage play The Diary of Anne Frank (Goodrich & Hackett). In that scene the new people who arrive in the Secret Annex are the Van Daan family:
- Mr. Van Daan (Hermann Van Daan)
- Mrs. Van Daan (Petronella Van Daan)
- Peter Van Daan

How they seem to be adjusting (based on what we see in Scene 2)
- Mr. Van Daan: Pragmatic but rather self‑centered and irritable. He shows a concern for practical matters (food, security) but also a tendency to complain and act selfishly — gestures that foreshadow later friction. He tries to maintain control and dignity but is clearly tense about the cramped, risky conditions.
- Mrs. Van Daan: Nervous and clinging to small comforts. She reacts emotionally to the loss of privacy and comforts, is easily upset by the restrictions, and looks to the others for reassurance. Her manner shows anxiety and dependence.
- Peter Van Daan: Shy, awkward and withdrawn. He seems uncomfortable with the forced intimacy and the presence of strangers in such close quarters; he is quiet, embarrassed, and tends to retreat (he also has his cat, which gives him a small comfort and a private focus).

Overall mood in Scene 2: relieved to be hidden but anxious, constrained and aware of the danger; the Van Daans are trying to settle in but already showing the strains that the close, secret life will create (bickering, irritability, withdrawal).

If you meant a different edition or the book (novel) rather than the play, tell me which and I can give more precise page/line references or quotations.
