    shift
    case "$CHOSEN_KEY" in
       1) echo TEST1 ;;
          if [ $CHOSEN_KEY -eq 1 ];
          echo TEST1 ;;
          then
          echo "Select Version"
          echo "[a] - Version 6"
          echo "[b] - Version 7"
          echo "Please enter your option: "
          read "CHOSEN_VER"
          if [ "$CHOSEN_VER" == "a" ];
          then
          echo " You have chosen Version 6 installation "
          elif [ "$CHOSEN_VER" == "b" ];
          then
          echo " You have chosen Version 7 installation "
          else
          echo "Select proper category"
          fi
          fi
          break;;

There are several problems here. Note the code marked in red above.

First the 1st ";;" on the first line of the actions for case 1 terminates the actions for that case. Having an if statement following that is not allowed. I assume you should just remove this ";;".

Second, you are in the actions to be performed when $CHOSEN_KEY expands to 1; so why do you need to test whether $CHOSEN_KEY still expands to 1 one line later?

Third, you have an echo statement after an if statement before the then keyword. And, it ends with another ";;".

I'm guessing you want something more like:
Code:
while [ $# -ge 1 ]
do
    CHOSEN_KEY="$1"
    shift
    case "$CHOSEN_KEY" in
    (1) echo TEST1
        echo 'Select Version'
        echo '[a] - Version 6'
        echo '[b] - Version 7'
        printf 'Please enter your option: '
        read CHOSEN_VER
        if [ "$CHOSEN_VER" = "a" ]
        then
            echo ' You have chosen Version 6 installation'
        elif [ "$CHOSEN_VER" = "b" ]
        then
            echo ' You have chosen Version 7 installation'
        else
            echo 'Select proper category'
            # I am surprised that you do not exit here instead of continuing???
        fi
        break;;
