I have nine plumeria plants, grown from seed five years ago. Currently they are about 12" tall. However they are still only producing fresh leaves from the apex. I wish to get flowering branches from these plants, can you please advise how to achieve this, and how long before I can expect flowers. Currently, the plants are growing indoors, in pots, on a sunny window ledge.
Plumeria naturally branch after blooming, but for optimal flower production and to create sturdy, attractive plants, it may be necessary to branch plumeria by pruning.
Wait until early spring to prune plumeria before new leaves emerge.
Observe the plumeria plant and see what branches can be pruned to improve the overall shape. Look for diseased or spindly limbs as well as limbs that cross over other limbs. Decide if the plumeria is the right height for your location.
Remove the weak or diseased limbs by cutting back to a main branch. Leave one inch of growth between the main branch and the cut area. The wound will emit a considerable amount of sap, which will dry up along with the remaining branch.
Cut the main stems back to the desired height or length. Cut 1/2 to 1 inch above a leaf node or joint at a 45-degree angle. The leaf node is the raised or ridged area along the branch below the cut where a new branch will emerge.

My plumeria has been in the ground for three or four years; we live Inland North County San Diego. The only branch on my plumeria has a shriveled area in the middle of two seemingly healthy areas. It started showing leaf promise a couple months ago but hasn't progressed any further. We had several blooms and leaves last year and were very hoping to have more this year.
I'm listing several articles that will help you access the growing conditions.

trunk, can I take it off and plant it? It is about 3 or 4 ins. tall and has 8 leaves on it
That is probably a sucker off of the root crown and has no roots of it's own. aIf it was a seedling, you could just dig up and re-plant with relative certainty of a successful transplant. But with a sucker, you will have to cut it and treat it as a cutting to be rooted. There is maybe a 50/50 chance at best that it will take.

my seed pod just open can I plant them now
Now can be ok, since you are inside of their native zone. Spring will be best, but the seeds will get less viable the longer that they sit. There should be no problem with planting these now.
These seeds are highly unreliable, though. It is much easier to start these plants from cutting instead. But it will not hurt to try them from seed.

One plumeria is 2 years old and the other 1 year old -- both produced flower clusters this year although not every flower matured to a flower..... On the plant that goes straight up.... this one is now about 5 ft tall... I was thinking of pruning it but am afraid.... Your thoughts?
Although it is not necessary to prune them, it would not hurt to do so. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/flowers/plumeria/plumeria-pruning-info.htm
I bought my Plumeria in March at the Home Show in March and it has no leaves and the top is turning black what should I do?
This sounds like a fungal/bacterial issue! This should be corrected as soon as possible. I have a recommendation, and recipe that I use, personally for occasions such as these. The recipe is as follows:
First, you will want to prime the soil with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.
Here is an article that will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/flowers/plumeria/growing-plumeria.htm
