Could two binary planets become habitable under these conditions?

If two planets (roughly Earth sized) in a binary planet system were tidal locked with one another what would be the necessary orbital angle and degree of axial tilt of each planet to satisfy the following circumstances?

1. At least one planet has a large habitable zone (Earth-like climate) on the light side with mild seasons from which the other planet can be seen during the day.

2. The day cycle of the same planet should be between 20 and 30 hours.

3. The sun could be seen setting behind the other planet, and the corona of the sun could be seen each night.
