Items From Collection Using "For-Each-Next" Loop

i have 3 questions related to the case below:

I have the next code and i`m using For Each-Next loop technique.
Somewhere i read that "For Each-Next" is slower than "For-To-Next"
loop. I have to put items from a collection in specific cells location
fill a matrix or fill an array.
Question:

1)Is possible to do the same job without use "For Each-Next" loop?
2)How can i extract items from collection like they were a matrix elements?
3)Can i extract, for example, the 4th, 5th or 11th element of one collection if i want?

i=1

j=1

For Each Item in Collection

If j
