the guzmania and neos are epiphytes and can just be tied to a branch or attached to the background. so is the staghorn. the bird' nest, i would remove as many OUTER leaves as possible if you receive it in a larger form. then plant it in a pot. the dracaena is the same just plant it. the pothos, you can either plant the cut end, place the cut end n your water feature (if you have one) and let it grow out, or just lay it where you want it to grow from. pothos and philodendrons are amazing plants and can even be planted under water, and they will eventually gro themselves out of the water. you may also want to consider a small vining plant as well, such as a ficus pumilia (creeping fig) or a rhaphidophora species.
