Make sure that no crons are running within 5 min from one another.

Your set up will not work.
5 minute and 10 minute will always conflict. As will the 15 minute and 10 minute. etc.

If you know what you are doing, make one script with an info file that stores a number.
Retrieve and update number every time script is run.
Always do your 5 minute stuff.
Number even, do your 10 minute stuff.
Number divisible by 3, do your 15 minute stuff.
Number divisible by 12, do your 1 hour stuff.

That way you only have one cron job. Run every 5 minutes.

You can also specify more specific run times for each job using "," for a set of times, "-" for a range, and "/" to skip intervals. See the X10 Wiki article on cron jobs for more info and samples. In this particular case, "," is what will be of most use.
