Hi that’s what I found on various websites (rewrite by me)
It was a long and challenging tasks for me but here it is !
Anubis: "Inventor" of mummification, which he practices for the first time on Osiris, Anubis is the protector of the dead and of the necropolises. Guardian of the gates of the beyond, he welcomes the deceased and accompanies them into the underground world. Considered then as "the conductor of souls", he nevertheless plays an important role in the underworld. He protects the deceased, welcomes them in the afterlife and leads them before Osiris, with whom he proceeds to the judgment of the dead by taking care of the weighing of the heart. These functions are worth to him to be named in turn "Lord of the land of dawn", "the Opener of the ways", "the Master of the secret" ... Anubis is the undisputed master of all the rites and of all mummification techniques. He is the god of embalming.
Isis: Isis is revered for her cunning, intelligence and tenacity. Source of life, she is "the Great Mother", the embodiment of the creative power to which we owe the Earth and all living beings. From the New Kingdom, Isis was worshiped as the Universal Mother and consoler, and became the most popular goddess in Egypt, where her worship took on considerable importance. The Egyptians give Isis a special worship and show her immense piety. The Isiac religion will gain Greece, Rome then its Empire and will give way only to Christianity.
Osiris: Originally worshiped as a god of plant forces, Osiris enriched his personality over the centuries. A dead and deified king, Osiris also personifies the continuity of power and the divine essence of royalty. In the hereafter, he presides over the tribunal which judges the earthly acts of the deceased. Their verdict depends on their happy survival or their damnation. Popular mythology has built a legend that tries to reconcile the different aspects of his personality. Osiris is the god whom the Egyptians worship with the greatest fervor. His cult will even reach Greece and the Roman Empire.
Rê: Master of the gods, Rê travels the sky from east to west to generously dispense the light and heat of the sun. In his person, venerated throughout the country, he summarizes the three phases of the course of the star of the day symbolizing the three essential moments of human life, childhood, adulthood and old age.
Oupouaout: again covers a territorial symbolism, Oupouaout being responsible for protecting "The Sacred Land" (ta-djéser), in the company of his colleague Anubis, with whom he shares the appearance of a pseudo-jackal and to whom he assimilates to the over the ages.
