The first one is Epipremnum aureum, which we call Pothos on this side of the pond. It's a staple plant. It doesn't die, you can't kill it, it grows and survives all but the worst conditions. In other words, it's great for terrariums with jumping geckos, even leachianus, but I wouldn't use it for herbivores. The plant does have calcium oxalate which can cause problems such as burning in the mouth or swelling tongue. The sap can also cause skin blisters if you're sensitive enough. I've used it 'forever' in my enclosures and it's never caused problems with the animals nor me.
The second one is one of the Wandering Jew plants, Tradescantia species. Most common species is zebrina, but it's got striped leaves, though some do have solid green. It's easier for you to ID it since you have the plant and can look for the small details. It can be used, specially in darker enclosures since it can take low light. However it's flimsy and breaks easily. On the other hand, the broken pieces easily root, giving you a whole new plant in record time (I consider this and the first one to be the indoor versions of Kudzu. :lol: )
Third is Kalanchoe, again it's difficult to say which one without seeing more of the plant and flowers. It's possible to use in a terrarium if you need a succulent, but it breaks relatively easily, so don't use it for big bodied lizards or jumpers.
The fourth one has me boggled, no clue right now. The last one looks like a variation of the first one, as you mentioned, but something about it makes me wonder. It's probably a close relative, but just doesn't seem like a Epipremnum (though I'll admit that I'm just guessing at that).
