I'm not positive that I'm correctly envisioning what you mean by "above the node" cuttings. Do you mean that you planted a node beneath the soil? If so, that should be fine. You know those little brown nubby things that appear along the stem of pothos? Those will become roots. I have had pothos stems just shrivel up, instead of rooting, but not if those little brown nubby things are in the soil, or even right on top of the soil surface. It's really pretty hard to miss with pothos. They're among the "weeds of the house plant world". Not to imply that they aren't pretty. I have several pots of it in my home.
ETA: Wait! I looked at your pic again, and I got it! Duh! I think all of those cuttings will root just fine for you.
Your variegated plant (the one with the bi-colored leaves) will turn solid green if you don't give it bright enough light. Give it plenty of light and the variegations will become very noticeable. Don't put the plant in direct sun, but a spot to one side of a bright window will make it happy. Until it forms roots, however, keep it in slightly dimmer light, perhaps a few inches farther away from the bright window.
Your pothos will root easily in water, as many plants do. However, the roots that form in water are different that those that form in soil. They are more brittle than "soil roots" and break easily during the potting process. They may even die once the plant is potted up in soil. I prefer to just insert my starts in a rooting medium ... usually whatever standard potting mix I'm using at the time. Keep it moist, but not soggy, until you see new growth on the plant. That will indicate that enough roots have formed to support a new plant. At that point, begin allowing the top 1/2" to 1" of soil to dry, before you water again. Always give the plant plenty of water, so that the entire root ball is moistened. Then set the plant aside and allow all excess water to drain away. Never let plants stand in saucers that contain water.
HTH!
