You can keep a second array, indexed instead of associative, and use
that as the list of indices into the associative array.

choices=(a b c d e)
declare -A choicelabel=(
    [a]="Alan" [b]="Betty" [c]="Charlie" [d]="Doug" [e]="Ethel"

for i in "address@hidden"; do 
    printf '%s: %s\n' "$i" "${choicelabel[$i]}"
