You have to be careful not to enter a number that is out of range. (zero or greater than the size of the list)

I made a few changes to catch that error and another bug I discovered...
Code:
function name {
echo
echo "Which name you want to change? "
read iname
[ $iname ] || output;    # No entry = exit
if [ $iname -gt $SIZE ] || [ $iname -lt 1 ]; then
    echo "Choice is out of range"
    listname;
fi

Code:
function listname {
num=0
for x in ${NAMES[*]};
do
    num=$(( $num + 1 ))
    printf "%d-%s" $num $x
    if [[ $(( $num % 4 )) -ne 0 ]]; then    # 4 column display
        printf "\t"
    else
        printf "\n"
    fi  
    SIZE=$num
done

Code:
NAMES=($(cat names.data | sort -u))     # unique names array
SIZE=0

function output {
echo
for x in ${NAMES[*]};
do
    echo "$x(${AGES[$x]})"
done
exit
}
