At the risk of being blunt, those should not be planted together - not unless you're up for a challenge, and probably not when you're just starting to learn the ins and outs. Dionaea need entirely different conditions than the others throughout the year. D. capensis and binata are rapid spreaders and in the same container will likely overwhelm the others and eventually one will choke the other out. Mexican Pinguicula do not do well in the media enjoyed by the others, and they are particularly touchy when planted in undrained containers. With cleverness and attention to pruning/pinching sundews trying to overtake the others, you might be able to make any two of these work together in the long term, but it would be a challenege.
None of those plants particularly need the shelter and heat a terrarium provides. All but the most icy, bone-dry homes should be fine for all of them during active growth. (Provided there's plenty of light - insufficient light will make almost any plant touchier and more demanding.) Whereabouts are you? What's the climate like outside, in terms of seasonal high/low temperature and humidity? What are the ranges in your home? What kind of rainfall do you get locally? The best way to answer the question of which plants you can satisfy is to start from the conditions available to you naturally and work outward from there.
Your terrarium could grow alright for the first several months or maybe a year, but if you're insistent on not digging it up, you should start reading about how to clone your plants vegetatively so that you can keep back-ups elsewhere. Fortunately, all the varieties you have listed are relatively tough plants and propagate readily with the right technique.
Best luck,

PS - My personal recommendation would be to leave the capensis in the terrarium - once it flowers it'll fill the terrarium to overflowing in remarkably short order, and capensis will probably tolerate an undrained container better than the others. D. binata can use the same potting mix but does best in a tall pot or hanging basket where you can appreciate the drooping foliage (in the terrarium it'll look cool too but it'll turn into a sticky tangled mess if you ever have to prune/cut dead leaves/rescue the others from being smothered, which trust me, you will.) Your flytrap and Ping will be easier to please in their own containers, where you can give them the specific types of potting mix and watering routines they enjoy.
PPS - We're a hard group to satisfy. Don't be surprised if you can't take everyone's advice. XD
