I just want to know if they will grow in Texas.
The USDA hardiness zone for Houston is 9a. Kousa dogwood is listed as hardy to zone 8. So there's a chance that it may too warm for them in Houston. However, I would check with the local County Extension Service for advice specific to your area. This link will help you locate your nearest office: https://www.gardeningknowhow.com/extension-search/

We bought a Satomi Kousa dogwood and the young bracts are white. Will they turn pink or is the tree mislabeled?
The bracts should be pink to red in color. However, I did find the following nugget on a university web page that might explain your white bracts - environmental conditions do sway bract color:
"'Satomi' (also listed as 'Rosabella') - This is a very popular cultivar said to develop bright pink bracts. In the United States, however, the warm summers seem to dull the color. As a result, most plants bloom light pink or white-pink. The color can vary from season to season, but 'Beni Fuji' probably has deeper pink bracts."
My 3-yr old, apparently healthy, Kousa pink dogwood never bloomed. Why?
I wouldn't worry too much yet. Three years is a bit young for blooming expectations. Your tree probably isn't mature enough yet to bloom. Young trees spend a few years establishing their root system before investing energy towards blooming.

When should my Kousa Dogwood begin to leaf out? I live in zone 5-6 and there are no leaves on the tree. This is the second dogwood planted and I am getting worried because there are no leaves on the tree.
Are the branches brittle and snap off when bent?
Do they bend? If you scratch the bark does it appear green?
A newly planted Kousa Dogwood requires a good amount of watering in the first 2 to 3 years to become established.
We did have an extremely cold winter in most of the entire United States and a new planting may not have been established enough to survive the temperatures.
Review the care and growing requirements in the article below.
I would provide water and watch and see.
Also most garden centers will replace a plant if it expires in the first year.
I would like to know the type of tree. I believe it is a Kousa Dogwood but not sure. What is your opinion on the health of the tree? My landscaper planted it last year in June and, to me, it looks under stress or partially dying.
I am sorry but we did not receive your photo. Can you offer more description - how does it look under stress/dying?
In the meantime here is an article on kousa dogwoods that may aid in your identification:
Help! I planted this tree two years ago, fertilizing with acid fertilizer in the spring and fall. The tree is growing well and appears healthy, but produces only a few blossoms (two dozen or so). What do you recommend?
My dogwood did not blossom too well this spring either due to the cold spring we had - the blossoms are very tender to the cold. Drought could also affect blossoms. These and other reasons are discussed in the following article:
This is my 3rd season for my pink kousa dogwood. This year the flowers were a very pale pink, almost white. Is there anything I can do to keep it producing deep pink flowers like it had the 1st year?
Your soil pH may not be acidic enough; pink dogwoods do best when the pH is below 6.5. I recommend that you test the soil around your tree. To lower the pH you will need to add aluminum sulfate, and you will probably need to do it for a few years at least as pH adjustments happen slowly over time. To get a soil test you can contact your local extension office which you can find using the following link: https://www.gardeningknowhow.com/extension-search/
