1. looks like Spathyphyllum (Peace Lily) 2. Maybe Beaucarnea recurvata (Ponytail Palm)? What does the trunk look like? 3. Looks like a Christmas Cactus or similar - that would be Schlumbergera, or Rhipsalis, most likely.
Looks like: Aspidistra elatior, Cast Iron Plant; Beaucarnea recurvata, Ponytail; Difficult to tell from the blurry photo but either Schlumbergera truncata (syn. Zygocactus truncatus), Christmas Cactus or Hatiora gartneri (syn. Rhipsalidopsis gartneri), Easter Cactus.
