I believe that magic and science are, in a way, interchangable. It used to be believed that many phenomena were the result of magic, but science has slowly begun to find explanations for these. I believe that there will be many new explanations as time goes on.
Before I say this next bit, let me state: I do believe in God. I believe very strongly and sincerely. But, if there were an explanation found for how we came to be here on earth, I would be willing to believe it. Gandhi has said a similar thing: if science somehow proved that his belief of reincarnation was incorrect, he would believe the science.
I don't believe in a "Super Soul". I believe in "souls", but more as an abstract and intangible part of human beings, like a conscience or that proverbial "voice in the back of your head". This is why I would disagree with your list of "Super Souls".
Mother Teresa was definitely a nun who worked for good according to her faith. Think of this: when people were dying under her care, she would often baptise them before death. This was never a choice made by the dying, many of whom were Hindu and Muslim. She went against their beliefs by baptising them, something most people would agree is wrong. There is a lot of controversy about exactly how much good she did do. I'm not sure that she could be a so-called "Super Soul" when her means only justified her end, and not the end of the people she helped.
I believe Sharpies has pointed this out, but the Buddha (I am assuming we are talking about Siddharta Gautama, and not a different Buddha) did indeed leave behind a wife and child. If we ignore that, I'm sure he definitely was a good man. Religion has always been an integral part of India's culture, and committing yourself to spiritual enlightenment was not something odd to do. The Buddha just found a different way to do it, because he didn't agree with the Hindu caste system. This doesn't make him a "Super Soul". In theory, anyone could achieve what he did.
I'm not going to spend a lot of time talking to you about Jesus Christ, because it's obvious we won't agree. I don't believe that Jesus was the son of God, or any sort of messenger. I believe that he was a Jew who did some good things, and met a sad end; but according to the laws of that time, blasphemy was punishable by death, and by Jewish law, Jesus was committing blasphemy. In Jewish law (and by my beliefs), it is considered heresay to believe that God is divisible. Since Jesus claimed to be the son of God, and also God the son, he was claiming that God is a divisible entity. I believe he was just a man, not a "Super Soul".
Mahatma Gandhi is certainly a peace-loving man. He was raised in a place where peace was of the utmost importance, and from birth has been groomed for this role. He is not a "Super Soul", but certainly a wonderful person. He has responded to persecution and death by rebelling, which many other people have done. This is an obvious response, not a sign that he is somehow spiritually, magically, richer than any person.
And then there are things such as telepathy. I believe that telepathy isn't possible; accurate assumptions of a person's thoughts are. Especially when you know that person very well.
Reiki, I think, is more of the sufferer taking on the feelings of goodwill from the healer and using them. These feelings of goodwill are interpreted by the person receiving them, and it will give the person a hope, a strength that they can create within themselves in response. My best comparison would be: if someone is upset, and you crack a joke and laugh, they will eventually join in the laughter and feel better because of it.
