Try sth along this line (and expand):
Code:
awk     'function min (M, V1, V2) {if ((!M) || V1<M) M=V1; if (V2<M) M=V2; return M}
         function max (M, V1, V2) {if ((!M) || V1>M) M=V1; if (V2>M) M=V2; return M}
                        {NI[$1]++
                         Min[$8]=min (Min[$8], $9, $10)
                         Max[$8]=max (Max[$8], $9, $10)}
         END {print "Numfile: ", NI[$1], "| D"$8"   min=", Min[$8]," max=", Max[$8]}
        ' file
Numfile:  8 | D4   min= 9  max= 7392
