What material is used to make the interior sidewalls panels, ceiling as well as luggage bins in a commercial aircraft?
The materials used in aircraft are similar regardless of airline or type of aircraft, since all passenger-carrying craft must meet  flammability requirements.

The side panels, the ceiling and the luggage bins are made out of a Glass Fiber Reinforced Plastic (GFRP) that must meet fire/smoke/toxicity (FST) requirements.The small window shade panels that slide down to cover airline windows, are typically thermoformed polyetherketoneketone (PEKK) plastic sheet. Some other high performance thermoplastics can be found on an airliner's interior, like the polyetheretherketone (PEEK) and the polyvinyl fluoride (PVF) (mostly as decorative surfaces laminate).
