They look rather light starved, but I could be wrong.
By the way, you have your pitcher plants flip-flopped. The third pic is your nepenthes (looks like N. ventrata?) and the fourth pic is a very distressed sarracenia (a Scarlet Belle perhaps?). I think that the sarracenia needs some good sun-bathing to perk it up.
A nice start at a collection-good variety. I don't see why any of these can't pull through.
