First, the plants shown in the smaller photo of the entire tank: the left is Java Fern, then a plant I am not certain of but suspect is not aquatic, then a crypt (prob the one you thought was pygmy chain sword?) and then the variegated (spotted leaf) sword (Echinodorus sp). The crypt looks fine, the Java Fern and sword do not.
The Java Fern should not be planted in the substrate, it will rot; it needs to be attached to wood or rock (or similar decor), cotton thread will work to do this, and eventually the plant's roots from the rhizome will attach it firmly to the rock or wood.
The sword is one of the red spotted leaf varieties. Swords usually lose their existing leaves when moved from the store tank to your aquarium, and as long as new growth emerges from the centre of the crown it is growing. I can see a new leaf in the photo. However, the plant's crown is below the substrate. If you gently pull the plant up to just expose the crown (the white area where the leaves emerge upward and the roots downward) it will be better.
If the water is 74-78F, that is fine for the plants, normal community tank temperature is around 77-79F.
As for light, I can't surmise if the "bright room" is sufficient or not; it will be for the crypt, they are low light; and the Java Fern once out of the substrate should be fine. The sword would depend upon the intensity of daylight it receives, and I can't tell without being there.
As for a tank light, a single fluorescent tube T8 in a daylight or full spectrum (around 6500K) would work fine. Alternatively, you might want to look into incandescent light, with a couple of the Compact Fluorescent bulbs now available; they provide a lot of light intensity,more than normal incandescent bulbs, with very little heat; over a small 10g tank this would be more practical. CF bulbs come in various "colours" like daylight at 6500K as well. Either way, that would be more than sufficient light for plants in your 10g aquarium.
