There's syntax errors and logical errors. Having corrected the syntax, it looks like
Code:
while read line; do awk  -v var="$line" '{for(i=1;i<NF;i++) if ($NF==var) break; print var FS $NF }' searchfile; done < listfile

The result shows the logical errors, e.g. $NF is always the last field in the respective line
Code:
23 777
23 677
23 67
34 777
34 677
34 67
45 777
45 677
45 67
86 777
86 677
86 67

Sth. like
Code:
{for(i=1;i<=NF;i++) if ($i==var) print var FS i }
23 2
34 3
45 1

would come closer; still the "not found" missing.

However, as an awk- only solution, try
Code:
awk     'FNR==NR        {T[$1];next}
                        {for (i in T)
                                for (j=1; j<=NF; j++)
                                        if (i == $j)    {print i " matches " j " col"
                                                         delete T[i]
                                                        }
                        }
         END            {for (i in T) print i " not found"}
        ' file1 file2
23 matches 2 col
34 matches 3 col
45 matches 1 col
86 not found
