The current conception of the Orishas is highly adultered with Jew Age crap, which destroyed the original African relgions, though if we look at their meanings in a Satanic light, we can see through the crap, for eg (the below is just my own understanding of them, any other inputs are appreciated):
Eshu being allegorical for the Kundalini Serpent: his colours are black and red and he is the Orisha of fun, sexuality, revenge and human affairs. The youngest of the Orishas being the last to be created by the Supreme God Olorum (akasha/aether principle). As our kundalini, he is what connect us to our Gods, Satan part in us.
The other ones can be also allegorical of the chakras and their planets, being divided in Orun (heaven, the upper chakras) and Aiye (earth, the lower chakras), then we may have:
Ogum, the warrior and survivor, as the influence of Mars in our natal charts and the sexual chakra, same for his female similar known as Iansan/Oyah, who is the Orisha of sensuality, war and passion.
Omolu aka Obaluaye is very Saturnian in his characteristics, but he also brings cure to one, not only deceases and bad luck, and his colours are said to be white, red and black.
I'm not sure if Yemajah is related to Venus or Jupiter, but Oshum is more likely to be Venus/Throat Chakra/Aphrodite as the Orisha of love and kindness, than Yemanja, Oshum is also the Orisha of rivers which can be allegorical of the twin serpents mergin in the eyebrows and making the heart shape, which is of Aphrodite.
Xango/Shango is very likely the Solar Gods, is is the warrior whose symbol is the lightning bolt and who brings justice.
