Try this (but a sample could help !)
Code:
#!/bin/bash
Input="data.csv"
I=1
while read LINE
do    #~ find the string that starts with data7
    if [ "${LINE:0:5}" = "data7" ]
    then
        read LINE    #~ if the string on the next line has the word prisoner then replace it with the string in line 1.
        if $(echo "$LINE" | grep -q prisoner)
        then
            head -n$I "$Input" | tail -n1
            (( I ++ ))    #~ the next instance of the pattern would be replaced by the string in line 2 and so on.
        else echo "$LINE"
        fi
    else echo "$LINE"
    fi
done < "$Input" > OutputFile
