You've made enough posts on here to know that the denizens of the Christian forum can answer these questions at least as well as anyone here.
The
Naassenes (Greek Naasseni, possibly from Hebrew נָחָשׁ naḥash, snake)[1] were a Christian Gnostic sect known only through the writings of Hippolytus of Rome.
The Naassenes claimed to have been taught their doctrines by Mariamne, a disciple of James the Just.[2] The retention of the Hebrew form shows that their beliefs may represent the earliest stages of Gnosticism. Hippolytus regards them as among the first to be called simply "Gnostics", alleging that they alone have sounded the depths of knowledge.[3]
Delightfully obscure and weird, but not Jewish.
Etz_Chaim and [wiki]Etz_Hayim_(disambiguation)[/wiki] discuss the term Tree of Life in Judasim.
The [wiki]Tree_of_life_(Kabbalah)[/wiki] discusses the relationship of the Sephirot to the tree of life.
That's probably medieval.
Adam_Kadmon (Primordial Man; also Adam Ila'a, אדם עילאה "supreme man"; abbreviated as א"ק, A"K) , in Kabbalah, is the first spiritual World that came into being after the contraction of God's infinite light. Adam Kadmon is not the same as the physical, Adam Ha-Rishon (Adam, the first man), whom God created from the dust. The spiritual realm of Adam Kadmon corresponds to the sefirah (divine attribute) of Keter ("crown"). It is the divine will and program for subsequent creation.
In Lurianic Kabbalah, the description of Adam Kadmon is anthropomorphic. Nonetheless, Adam Kadmon is divine light without vessels, i.e., pure potential. In the human psyche, Adam Kadmon corresponds to the yechidah, the collective essence of the soul.
Also more or less medieval - note the wiki mentions Philo, Talmud and Midrash but that seems more on the lines of Man created in God's image, as opposed to a tree of life rap.
Compare the representation of the Sephirot to the pictures you are posting. Your pictures don't really belong in a Jewish forum.
