Sarracenia (trumpet pitchers) and Dionaea (VFT) both require a winter dormancy so won't do well in a terrarium unless you move them to a cooler situation during the winter. Do you have an unheated greenhouse you could use?
As for the Drosera (sundews), assuming they are sub-tropicals (most likley aliciae or capensis), they should thrive in a terrarium if given good lighting and humidity, or on a windowsill.
I don't grow Nepenthes (monkey cups), but the same conditions as the Drosera should be fine.
