How to grow Dendrobium anosmum in my area (League City, TX)? I am worried about winter.
Orchids can be tricky in that these exotic plants have very specific needs - namely heat and humidity. This is why most are grown indoors, as their chance of surviving over winter would be fairly slim, even in your area. That said, you can grow them in a container and bring indoors for overwintering. For more information on growing these indoors, this article will help: https://www.gardeningknowhow.com/ornamental/flowers/orchids/indoor-orchid-care.htm
I have some Dendrobium orchids but they did not bloom after buying. Should they be repotted or should I use some fertilizer? I use 19:19:19 and orchid boon by sprayer.
I will list some links for you with care and repotting information.

These are Dendrobium Orchids.

Congratulations! It sounds like your orchid is producing a keiki, or baby orchid. Here is more info about them and how to care for them:

My Orchid is producing flowers from the main plant stems, but one of the flowers is growing roots, what do I do? I have never had an Orchid before so am a novice at looking after it.
Your Orchid has developed a Keikis, or a baby!
Here is a link with more information.

I bought it from a nursery about a year ago, but they had it planted in regular soil,which I had never seen before. I always plant in a bark mix. But I left it alone, kind of an experiment! Now 2 keikis have sprouted near top of plant. Is it from stress? And should I leave them be or replant them? They both look healthy. Will they eventually kill mother plant? Thank you for any help!
You are right to be concerned about the potting mix for your Orchid, it is a good idea to change it out to a good quality Orchid potting medium and a suitable Orchid pot.
These links will give you information on this.

Congratulations on the new Keiki's!
They will not harm the parent plant, but you need to make sure they are mature enough to be removed and repotted.
