Your first question seems pretty obvious. I mean what you call 'defensive' magick is protection magick. What you call 'offensive' magick could be curses and etc.
I have no idea what soul magick is.
There was a forum post about faes not too long ago maybe check it out. It was about one or two days ago
Please define what you mean to say with royalty?
Magick is magick, and plenty of it works with psychological/spiritual selves. All magick is soul magick.
3) is it posssible to see and teleport to the faes?
Astral projection, hedge-crossing, shamanic journeying. These are methods to go to the otherworld, where spirits are.
4A) is there magical royalty?
No. Magick is the art and science of manifesting your Will and Intent, often but not always through a magico-spiritual practice.
It is no more capable of producing royalty as art, running, knitting, etc, is. Were there royals in history who practiced magick? Certainly.
4B) is there royalty in the fae world?
Largely depends on what you mean by fae.
If you mean some idealized tinkerbell, or some fictional race of pretty people, throw all of that out the window.
Fairy is just another word for spirit. What one person calls a Jinn/Demon/Fallen Angel in one theology, another would call a fairy/elf/troll in another. And they range from being the spirits of the dead, to fallen angels, to the wights of the land and nature.
Fairies come in a lot of shapes and forms, and the only "royalty" are powerful spirits that rule over spheres or concepts or are outright gods themselves.
The folkloric devil for example, known as the black man of the crossed roads or old Hobs, is often considered to be the King of Elphame or king of the fairies.
Or in another area of Europe, there was the Unseelie and Seelie courts.
To see your own aura place your hand aginst a white surface and watch it, dont think just watch. Eventually you will start to see a fuzzy white outline keep starting at that and eventually you will see an aura behind that.
Some people are lucky to be born able to see aura's. I think it may have to do with they're personalities or maybe brain synapse connections are just special.
