The first couple of plants and the last one look like S. purpurea venosa. They can grow in full sun and will become very red when exposed to light. These plants can grow with water up to traps and can even be submerged in water. I would suggest a very high water level, at least half way up the pot and expose to strong light.

The taller plants will develop with more light and the traps will generally support themselves in full light with plenty of water. They don't require quite as much water as the purpurea but still require high waer levels. It looks a little like a rubra although it is very difficult to tell when it has been grown in such poor conditions before you got it. It is more than likely a hybrid species.

Another important factor for these plants is a cool dormant period. The best method for those of you in tropical areas would be to remove the plants from pots, trim off the pitchers, and carefully wrap the roots in sphagum and refrigerate for around 3 months. This also promotes flowering. The plants will gradually decline if not given a dormancy period over time. If you have plenty of room in the fridge just remove the pitchers, cover the pot and put it all in the fridge.

BTW, the smaller pitchers that have developed in the upright plants are an indication that the plants are too dry and have not had enough light.
