An acronym is a set of letters that represent a longer phrase or name, like TMI for "too much information."
A set of letters is normally called an alphabet.
yes they can it will be like making new alphabet and have as much letters as the egyptians
an alphabet is a set of letters. All alphabets are composed of letters.
Why were the letters written? -
It depends on the number of letters in the set - which is not specified. If there are n different letters in the set, the answer is n*(n-1)*(n-2)*(n-3)*(n-4)

I could be wrong, but it looks pretty much like a Kawasaki Vin number to me. Had both bikes and it compares pretty much like one i had, i just looked it up in my notes and it has the same combination of numbers and letters - set out the same way. I would guess Kawasaki!
In a set, as it is usually defined, elements can't be repeated. "Mathematics" has 8 distinct letters, so your set would have 8 letters. The number of possible subsets (this includes the empty set, and the set itself) is two to the power 8.
None. Some letters have one or more but all the letters, taken as a set, have none.
When talking about sets, it is fairly standard to use Capital Letters to represent the set, and lowercase letters to represent an element in that set. So for example, A is a set, and a is an element in A. Same with B and b, and C and c.
