Aset and her Family
Aset (Isis) is a Egyptian Goddess of Magick,Moon,Sun,protection,children,rebirth,resurrection,Universe,Sea and many more her siblings are Ausar (Osiris) Lord of the Underworld (Duat) he is the lover and brother of Aset he is the Lord of the Dead but that doesn't mean he's evil or bad he's very misunderstood due to him being the King of the underworld he is the God of death,afterlife,truth,rebirth,life.
Nebet-Het (Nephthys) some call her the dark aspect of her but i see nothing dark about her there is not much known about Nebet-Het she is also a Goddess of resurrection,death protection she is a very protective goddess her presence is similar to Aset but its also different she is called upon to make things hidden do not confuse this with Amunet the hidden one ! She is the wife of Set her brother and had a son Anubis.
her brother is Set he is not a evil god before he became the god of Chaos he was a god of storms.
Very little gods in Egyptian were considered evil i do not consider him truly evil.
His wife is Nebet-Het.
Haroeris (Horus the Elder) he is the brother of Aset some say he is also the son of Aset and Ausar and some say they are separate Haroeris is the god of light,good,truth he is an important upholder of Ma'at.
These are the children of Geb and Nuit Geb is the brother and husband of Nuit Geb is the god of Earth and Nuit is the goddess of Sky and universe their parents are Shu and Tefnut Shu is the primordial god of Air and Tefnut a primordial goddess of moisture.
These are the children of Atum and Iusas Atum was the first god that came out of the primordial waters of Nu some say that Atum is Ra but they were two seperate God but now they are one Atum-Ra Atum is the God of creation.
Iusas is the primordial goddess of Birth she is known as the "Grandmother of all deities" i do not know much of the primordial goddess.
I don't normally work with Isis, and I know over time deities have gained rule over elements they once did not [like the Goddess Bastes was the Goddess of music and later of sex] but I don't think Isis was the Goddess of a few things you listed like the moon, sun, universe, and sea. Same with Osirus, the God of truth he is not, Ma'at is the goddess of truth, the human heart is weighed against her feather to gain entrance to the duat. My Egyptian mythology is rusty, so I would need to double check everything, but either way you should site your sources.
Aset was also a sea goddess sailors used to pray to her before going on voyages Aset is a Moon and Sun Goddess due to her having power over Ra she had power over everything and she is sometimes mentioned as the mother of the universe
As Neko stated previously Aset is not a goddess of the moon, sun, universe, and sea. Isis however is. This all goes into the debate on the differences between Isis and Aset, but I'll try to simplify it. Aset is an Egyptian goddess, Isis is a Roman/Greek goddess based on Aset. Isis can be a goddess of the moon, sun, universe, and the sea, because the Greek/Roman mindset equated Isis to Hera. Aset, however, is a goddess of the river Nile, a goddess of magic, a goddess of life, a goddess of mourning, a mother goddess, etc. There were no Egyptian gods of the sea, though there is a mention of a foreign sea god in the New Kingdom. Egyptians (before the Greeks came in and took things over) had little interest in the sea, it was basically a large, unending river to them, and considered highly dangerous. That is why in the tale of the sea mentioned above, gifts were given to the sea in order to placate it and keep it from encroaching on them. Isis, however, can be prayed to for anything, as she encompasses all things (syncretism was rampant). Also, while Aset may have held power over the universe, sun, and moon by being Werethekau ("great of magic"), she was not a goddess of these things. That would be akin to saying that because I know how to paint, I am an artist.
Wesir/Osiris is a Lord of Ma'at/ma'at (along with several other deities), but as with Aset he is not a god of Ma'at or of ma'at. To be a lord of something or to be involved in the process of something, is vastly different from being a god of that thing. If anything Djehuti/Thoth is more so a god of truth, as it is he that writes down the truths revealed by the scales of ma'at at the Judgment of the dead, while Wesir only observes the process. Ma'at is also a lot more than just justice and truth, and she and it are pretty awesome.
As for the whole:
I've never seen Wesir misunderstood for being a dead god.
There is quite a bit of evidence against Yinepu/Anubis being the child of Nebthet; it is evidenced that this is a later add on whenever the need for a triad of gods at each nome and temple became necessary. It's widely believed that this occurred in the New Kingdom, which is how Plato carried over into the story of Nebthet tricking Wesir into making Yinepu.
Set wasn't a god of evil, even after he killed his brother, and has always been a god of both chaos and storms (storms are considered chaotic in sunny Egypt). He became an evil god slowly over time as the cult of Wesir, Aset, and Heru-sa-Aset flourished and gained importance, while at the same time the Hyklos foreigners came in, took over, and used Set as the premier deity of the two lands (as he was similar enough to Ba'al).
Haroeris is a Greek name for Heru-wer (Great Horus), who was and is not Heru-sa-Aset (Horus son of Aset). These are the two basic forms of Heru's, but each of them has at least five additional forms. The two were not mixed/confused until the New Kingdom, and then were massively so after the Greeks took over. The information you've given could be applied to nearly all the Heru gods.
It would be more accurate to say that Geb is the Earth, and Nut is the Sky, as these are the earlier deities who personify concepts rather than being more civilization based. Nut isn't really a goddess of the universe as the universe includes the Earth. However, Nut does encompass the heavens and the Duat (the Nether-/Under-world isn't under our feet).
Atum and Iusas (or Nebethetpet in other cases) is existent at the beginning, however Iusas (and Nebethetpet) are usually placed as personifications of the right hand of Tem/Atem/Atum. Tem-Ra is not a common syncretic deity, as first Amun took over Tem's job, then Ra came into the picture. (Although there are a few cases of Tem-Ra.) I wouldn't say Tem is the god of creation, so much as he is one of the Creator gods (there are several, and one of them is even female), the same as I would say that Iusas isn't the primordial goddess of birth so much as she is the personification of the feminine creation energy.
Overall it's not a terrible introduction, but more research will reveal a lot more about these deities.
