You can use wait events too,
Oracle wait interface a practical guide to performance diagnostics tuning from richmond shee has a good example

dbms_profiler should help with your requirement. you may not be able to get the kind of granularity you want unless you fire the procedures one at a time and look at trace files.
this sounds like something coming down from management.... 95% of performance problems with stored code is either due to  

1. bad query
2. running a query 100,000 times when it should be run once.

you can probably use dbms_profiler to figure out was is taking the longest and tune from there.
