If there are no instances of your required processes they won't be listed in ps and therefore won't be counted by uniq.
Perhaps something like this will help you:
Code:
for p in process1 process2 process3
do
   printf "%s: %d\n" "$p" $(ps -e -o comm= | grep -F -c "$p")
done

How about
Code:
ps -e -o comm | grep -Eo "process(1|2|3)" | sort | uniq -c
