Is signal processing in mind hard to do in this world?
As compared to what? I'm assuming that what you are attempting to do is not something you've ever done before. If I'm wrong, then you need to tell me more about what you've done in the past that is either this or like this. If I'm right, then you would have no way of knowing whether this is easier or more difficult as compared with other worlds.
A sprite elder can do magic right?
Technically, you don't know what a sprite elder can do; you know what Lelach thinks a sprite elder can do. She believes that such elders represent the people in a way that enables them better to get answers to requests on behalf of the people. She does not know how that works, but probably would not call it "magic".
Can she teach me a song in spritish to ward of evil if it exists?
That would be magic. She does not know any magic.
Well if she define a person who have telepathic power is a monster then what does human think of sprite or vice versa.
Actually, humans think sprites are vermin who mimic human behavior. Humans kill sprites, apparently for sport.
So yes, sprites think that humans are monsters.
So it might help to think me as a gifted child from the King.
I will tell Lelach that the King might have some kind of plan for both of us.
This does appeal to her, and she relaxes some. It suggests you might be like Tonathel, one of the heroes in the writings who saved the sprites from the elves long ago. Of course, there's nothing about Tonathel in the writings that said he could use telepathic powers, but there were other heroes, and each was different, and even if none had telepathic powers that doesn't mean that such things are impossible for the King.
When I study my own mind, do I know how the mind reading skill works?
Yes. You are in essence tuning your mind to the frequency of the person whose mind you are reading, so that their thoughts come into your head. Once you know someone's "frequency" by tuning into them once, you can do it again, but until you know their frequency you have to know very precisely where they are relative to you so that you can focus on that spot--something you cannot do from your current position, as you can't even really be certain which way is up sometimes.
As to whether a blind person could use sound to locate a target, there's no way you could know the answer to that question.
Can I just randomly search for a mental frequency or is it there is no other mental frequency present other than Lelach's and mine?
There are more possible mental frequencies than there are all creatures of any kind including plants and microorganisms in the entire multiverse, and the precision with which you must target one individual frequency is so exacting that your effort might be comparable to trying to hit the center square on a checkerboard in Manhattan by throwing pebbles from Mars.
I will then try to ask the King for guidance for my situation by thinking about it.
I will ask the King about why I am here in the first place.
This will be like a dynamic meditation where I will try to ask myself the question and hope for a reply that come in form of intuition, dream or others.
I am assuming that this is a silent prayer-by-thought, and not an attempt at some sort of psionic skill. That would make it a prayer for guidance. Do you concur?
If so, for how long are you "praying", and apart from thinking these questions in a meditative and prayerful attitude, are you doing anything else?
Do I get the 1@1 Read Memories P1@1 skill or not?
If not, does it mean that the roll for it become the roll for 1@1 Enhanced Recollection P1@1 (read minds on self) or should it be re-rolled if any new info about the skill is known even if both skill are at P1@1?
Or do the read memories skill are needed as a prerequisite to do enhance recollection skill?
You taught yourself to read your own memories, a P1@1 read minds variant which is being listed as Enhanced Recollection. That skill does not work to read the memories of other people, and you have not to this point attempted to read anyone else's memories; you could, of course, attempt to read Lelach's memories, because you have her frequency. Doing so would be teaching yourself a new skill, but you would gain a bonus on the attempt to learn that skill based on the fact that you already know how to read your own memories, which is similar. That bonus would be the skill ability level you have on this skill, currently 1@1 (in addition to your BRA, your bias, and the world bias level, but minus the 1@1 target skill bias). If you improve your ability to read your own memories (which ordinarily takes months of disciplined regular practice) you will improve the bonus you would get for learning this other skill.
So the ability to read memories of others is not yet on your skill sheet, because although you have an example that will help you figure out how to do it, you've not yet actually taught yourself the skill.
I should add that in theory you can teach yourself how to do something without actually doing it, but it's rather difficult to describe doing that when you're talking about a psionic skill such as this. That's more common with tech skills, where you can learn everything you need to know to repair a device from a book, and thus have the skill even though you've never repaired the device.
