Answer 1

Your solution will work for generating the array. Instead of using a while loop, use a for loop:

#!/bin/bash
files=($( ls * )) #Add () to convert output to array
counter=0
for i in $files ; do
  echo Next: $i
  let counter=$counter+1
  echo $counter
done

Answer 2

# create an array with all the filer/dir inside ~/myDir
arr=(~/myDir/*)

# iterate through array indexes to get 'counter'
for counter in ${!arr[*]}; do
    echo $counter           # show index
    echo "${arr[counter]}"  # show value
done

Answer 3

You can do:

# use nullglob in case there are no matching files
shopt -s nullglob

# create an array with all the filer/dir inside ~/myDir
arr=(~/myDir/*)

# iterate through array using a counter
for ((i=0; i<${#arr[@]}; i++)); do
    #do something to each element of array
    echo "${arr[$i]}"
done

You can also do this for iteration of array:

for f in "${arr[@]}"; do
   echo "$f"
done
