See the following commands.

Ans1:


Code:
grep -c "PASS" fine_name

Code:
 sed -n '/PASS/p' fine_name | wc -l



Ans2:
Code:
cat fine_name | tr "\n" " " | sed -r "s/(.*) (FINISH.*)/\2/g" | tr " " "\n" | grep -c "PASS"




Ans3:

Code:
sed -n '/789/,/12345/p' fine_name | grep -c "PASS"

See the following code. to count the total number of "PASS" after matching the first occurrence of the "FINISH"


Code:
sed -n '/FINISH/,$p' pass | grep -c "PASS"

Using awk,

Code:
awk '/PASS/ &&  c++ && 0 END { print c; }' file

awk '/FINISH/ { f=1 } /PASS/ && f++ && 0 END { print f-1; }' file

awk '/789/,/12345/ { if(/PASS/) {c++;} }END { print c }' file
