It has baby leaves coming out on it. It is 4 feet tall above the bush.
It looks like a wayward stalk or perhaps something that had been growing there before the bougainvillea. You can prune the stalk back by about half to keep it in line with the rest of the plant. If the leaves look different from the bougainvillea and you think it is a different plant, you can cut it off at the ground or try to dig it up.

to transplant these beauties? It was a large Bougainvillea plant. I cut it into smaller sections, and it immediately went into shock, being surrounded by barriers until I could get everything contained. I began by stripping thorns and leaves. Herein lies the question: How do I successfully transplant this beautiful plant? I have already picked out the location. Thank you sincerely.
This will be transplanted just like most other plants, and can be done quite easily. These articles will help:

One branch took off growing. I would like to cut it and regrow it.
Get softwood cuttings from the plant. Here are more detailed instructions: https://www.gardeningknowhow.com/ornamental/vines/bougainvillea/propagating-bougainvillea.htm
I have a SW and a NW spot for planting. Which would be a better? I live in Seminole, Florida
They prefer warm, well draining, full sun locations, defined as much more than 6 hours of direct sun exposure in the summer months. In Seminole's USDA Zone 9b, you may encounter some winters in which the top growth is killed by cold temperatures if you do not winter protect so consider also growing it in pots. But you could try growing it outside too and annually prune off any dead wood killed by winter as I have one near me in Zone 8a that faithfully returns and blooms even with low temperatures of -2°F. That specimen is in a SW exposure. Of course, it starts to bloom slightly later than if winter did not kill the top growth.

What type of plant food to feed Bougainvillea?
You can use a balanced, slow release fertilizer like 10-10-10 or 20-20-20. Here is more:

I bought a 5ft bougainvillea from a nursery and the moment I took it home it started getting spider mites. I sprayed it with insecticidal soap and it was doing fine. But then I had a few days of windy and rainy weather and the bougainvillea’s leaves and bracts all dropped. It’s completely bare and I assumed it was from all the rain. I decided to repot it into a terracotta pot to help it dry out faster. However it’s still bare and some of the smaller branches where the leaves and bracts grew turned brown. I decided to prune those off and some of the stalks but I don’t see it showing new blooms or leaves at the nodes. The plant is still alive because if I scratch the bark it’s still green inside but I have no idea what to do. For reference I live in southern Ontario near Toronto so the weather is now warming up but we’ve had several days of temp fluctuations.
You have done all that you could, but make sure to keep spraying for mites. They are hardy and will not die with the first treatment. I'm battling them, constantly, all year. A little patience and care should get new growth going, but I would definitely focus on vegetative growth rather than blooming.
Keep in mind that you are well outside where it can be hardy. This means that your cooler weather is likely preventing growth, as well. Anything approaching 40F (4C) is going to seriously injure the plant.

this is the URL to the page with the photo: https://www.gardeningknowhow.com/ornamental/vines/bougainvillea/bougainvillea-garden-care.htm Is it a dwarf/mini, medium or large variety? Will it grow (well) along the bay side of the San Francisco Bay Peninsula against a 10-foot-high wall of a south-west-facing, non-heated garage?
It looks like Thai Delight, which is a semi dwarf variety that doesn't grow as tall as the regular bougainvillea. You are right on the edge of its hardiness range, so be sure to mulch it well before winter.
