Could this be the reason why it got so popular?
Do these symbols REALLY have spiritual power thats why they get used by alot of religions?
6-6-6? (Revelation 13:16-18)
Hexagram

These have nothing to do with Hexagrams or that 666 rubish. They're both symbols extremely common in Japanese/Korean culture.
I remember seeing variations upon variations of these sorts of symbols that were from the equivilent of heraldic symbols of Japanese families.- They'd be on flags and things and items of personal property etc I think. The little "6" type things are related to the Ying Yang, but symbols will often have 3 or 4 in them, not just two, always inside a circle. The origin is probably Buddhist.- Could be Taoist though, I don't know that much about the religious origins of Japanese symbolism.
Your so called "Hexagram" is much the same. Japanese have hundreds of flower type symbol variations.
The Green Hindu image of a flower below is totally different but you're making a spurious connection based on a superficial similarity- Hexagons are one of the most simple shapes in the world and nature and so aren't really related across cultures- They're in every flower, stone cracks, beehives, even on the poles of the planet Saturn. ;)
The Satanist star is 6x6x6 piles of purest poop. It was invented long after any "pagan" rituals it pretends to reference were long dead and done with. They likely stole their symbolism straight from the Jewish Star Of David since in Medieval times right until modern history Jews were regarded as dangerous heathens so therefore the latter-day "Satanists" chose that as a symbol of "occult" power. The goat is used because it's sometimes referred to negatively in the bible.
Same with your theosophical thing, once again you have people just cherry-picking other people's symbols so they can also appropriate the meaning and history along with them. ;)
Your merkaba is just the original Star of David- Very ancient symbol of the Jews.
Your Celtic cross is just the Christian cross with the Celtic decoration that symbolised the transformation of the Irish Celtic culture to the new religion.
Your Gnostic Abraxas incorporates a number of common symbols unique to the area of origin of that belief system- the cross of course being long used in different variations, as was the crescent moon.

They have
NO innate spiritual power unless you happen to
believe that they do. There are two main reasons that they are used:
1. They look good.
2. They're very simple designs handed down through the generations. They're a large part of our cultural history. As symbols they're also often shorthand for a lot more meaning. ie..The Christian cross isn't just a cross, it's also symbolic of the Christ sacrifice, suffering and the redemption of the human race... according to Christians.
