: a) Is there any function or variable that tells me which is the

The super user is always UID == 0. By definition.
The root account typically is 0, but doesn't have to be.
User accounts typically aren't 0, but can be (cf toor).
Any account with a uid of 0 is a super user.
It is the super user that gets all the toys.
: b) Can normal users look for system processes or kernel threads?
Sometimes. See the sysctls security.bsd.see_other_gids and
security.bsd.see_other_uids.
: c) Can root look for system processes or kernel threads?
If it is the super user, yes.
