Usually there is a process for every account, every contact source, every 
calendar source and in 4.7 three processes feeding Akonadi data to the 
Nepomuk indexer (contact, calendar, email). In KDE 4.8 there is one nepomuk 
indexer for all of those (and it is more optimized).
 There is also the Akonadi server process and a small helper "control" 
process for the server.
 If you see an akonadi_agent_launcher, look the whole command line for the 
real process name. This is like kdeinit4 for the rest of KDE.
 If you want more specific answer, ask which process you are interested in.

Nepomuk is used by KMail (and many other parts of KDE) to do searches in all 
kind of data. Inside KMail it is used for full text mail search and for 
addressbook search in the KMail composer.

Sorry, don't know the details of nepomuk. The configuration settings are in 
System Settings->Desktop search. How well they work, how fine you can tune, 
can't tell. But there are still some issues with it, and nepomuk sometimes 
goes crazy and uses 100% CPU (see a recent mail on the kdepim devel list).

AFAIK, you will lose full text search for those mails.

Nepomuk gets data from multiple places (feeders). Strigi gives that from the 
file system, the akonadi feeders give the data from akonadi data.

I hope this clears up some things.
