After the death of Hebert W. Armstrong, the Worldwide Church of God began to embrace a more orthodox understanding of the Christian faith. Armstrongβs successors, Joseph Tkach, Sr., and Joseph Tkach, Jr., have led the Worldwide Church of God in a more orthodox direction, rejecting British Israelism, accepting the Trinity, etc. The organization/denomination now refers to itself as Grace Communion International. A brief history of the transition from Armstrongism to Grace Communion can be found here: https://www.gci.org/articles/a-short-history-of-grace-communion-international/
Not every Worldwide Church of God congregation became a part of Grace Communion International. Those who chose to remain more faithful to Armstrong's teachings formed the United Church of God (UCG). In 2010, another group, the Church of God, a Worldwide Association (COGWA), split off from the UCG. Both groups retain Armstrong's original denial of the Trinity.
I have been unable to find specific information on the various churches you listed, but it would seem that the two mentioned above rejected the Trinity doctrine.
The following link shows the organisational splits, but the print is so small I can't read it! https://archive.gci.org/articles/worldwide-church-of-god-organizational-splits/
