The images are fairly low-resolution, so I am generalizing somewhat, based on what I see in the larger plants.
Many of them look severely dehydrated. Watering with plain water is fine, but if you have good root growth, then you need to water more effectively. Each time you water, flush water thoroughly through the medium. Then, water again when the medium is nearly dry again. For very dehydrated plants, don't be afraid to soak the roots of the plants a good long while (up to an hour at a time is a good place to start).
If your relative humidity is real low (Minnesota, I'm guessing central heat?), Use a humidifier or some other means to increase humidity.
For the small bare root plants, they are unlikely to survive like that for long. If you want to grow bare root in a pot, try a terracotta pot, which will retain some moisture/humidity after watering.
Shop light fixtures can be fine for growing, 6500 color temperature 'daylight' bulbs are best, but you can get started growing leaves and roots if you bought something else. Your plants are way too far from the bulbs though. I am fairly certain the lights didn't burn the Oncidiums unless the leaves we're touching or nearly touching the bulbs.
That's a start; good luck, you likely will get other suggestions.

I'll have to take some serious action on them being dehydrated  I didn't know it was that bad. I do have some orchid fertilizer that I got from an orchid nursery here so I'll start using that. I'm not sure why I was afraid of it.
Thank you for all the suggestions! All of this was so helpful. I really appreciate it  I feel totally blind in this so the direction is great. Thanks again!
Edit: Yes central heat

I wouldn't worry about the fertilizer right now. You need to get some water into the plants.
When you do provide fertilizer, if the package says give 1 teaspoon per gallon, use much less; maybe 1/4 or 1/8 teaspoon. Orchids are very weak "feeders", in general.
The fertilizer should provide N, P, and K, the N and K should be about equal, P lower (if your N-P-K numbers are different, don't worry too much about it).
When providing fertilizer, don't do it too often. There's an adage among orchid growers, "weakly, weekly" to describe how & when to provide fertilizer. Most growers I know provide fertilizer less often that that. Maybe monthly.
Above all, have fun, you'll get the hang of it, and don't stress if you lose some plants along the way.
