Reduce the number of lines by using Array

I have the following code to count the number of how many times the name occurred in one file. The code is working fine and the output is exactly what I want. The problem is the real code has more than 50 names in function listname which cause function name to have more than 50 case ,and function setname more than 50 lines.

is there a way to rewrite function name and function setname in short code? someone told me I can use Array but not sure how. My goal is to reduce the number of lines.

Code:
function listname {

echo "List of Name:-"

  echo "1-Kim    2-Lee     3-Jack     4-Sam"
  echo "5-Nick    6-Smith"

name;
 }

function name {
  echo "Which name ou want to change?"
        read iname
 
        case $iname in
        1 ) echo "Kim"

               read -p "Enter Kim: " Kim
               echo "Kim=($Kim)"
        ;;
        2 ) echo "Lee"

               read -p "Enter Lee: " Lee
               echo "Lee=($Lee)"
     
        ;;

        3 ) echo "Jack"

               read -p "Enter Jack: " Jack
               echo "Jack=($Jack)"
        ;;

        4 ) echo "Sam"

               read -p "Enter Sam: " Sam
               echo "Sam=($Sam)"
        ;;
        5 ) echo "Nick"

               read -p "Enter Nick: " Nick
               echo "Nick=($Nick)"
        ;;
        6 ) echo "Smith"

               read -p "Enter Smith: " Smith
               echo "Smith=($Smith)"

        ;;
   
        * ) echo "You did not enter a number"
                echo "between 1 and 6." 

esac
 echo "Do you want another change?"
 read anothchang
     case $anothchang in
        [yY] | [yY][Ee][Ss] )
        listname;
             ;;
       [nN] | [nN][Oo] )
        setname;

}


function setname {      
               [ -z "$Kim" ] && Kim="cat /tmp/list | grep -c Kim"
               [ -z "$Lee" ] && Lee="cat /tmp/list | grep -c Lee"
               [ -z "$Jack" ] && Jack="cat /tmp/list | grep -c Jack"
               [ -z "$Sam" ] && Sam="cat /tmp/list | grep -c Sam"
               [ -z "$Nick" ] && Nick="cat /tmp/list | grep -c Nick"
               [ -z "$Smith" ] && Smith="cat /tmp/list | grep -c Smith"
output;
    }

 function output {

 echo "Kim ($Kim)  
   Lee($Lee) 
   Jack($Jack) 
   Sam($Sam) 
   Nick($Nick)   
   Smith($Smith)"
  }
echo "Hello"
listname;

NAME
uniq - report repeated lines in a file SYNOPSIS
uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ] DESCRIPTION
Uniq reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are removed; the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found; see sort(1). If the -u flag is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of just the repeated lines is to be written. The normal mode output is the union of the -u and -d mode outputs. The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of times it occurred. The n arguments specify skipping an initial portion of each line in the comparison: -n The first n fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab charac- ters separated by tabs and spaces from its neighbors. +n The first n characters are ignored. Fields are skipped before characters.
