I believe that:
1. run ping1 one minute past every hour
2. run ping2 every 4:02 am
3. run ping3 every Sunday at 4:22 am
4. run ping4 every first day of month at 4:42 am

cheers

the fields in crontab (the first 5) are like this

first = minute
second = hour of day (can take 24 hour format 0 & 24 are the same)
third = date in month (1 to 31)
fourth = month (1 to 12)
fifth = day of week (0 to 7 where 0 & 7 indicate Sunday)
