a function for debugging on a cluster that saves all the objects inside the
whole stack of function environments and would also like to retrieve the names
of the respective functions. Perhaps also a method to simply retrieve the name
of a function inside this function could give me hints to the solution.

I'm not sure I understand what you're asking, but I think the answer is
no.  You can retrieve the name of a function by calling sys.call() (or a
related function for more information, see ?sys.call), but that has to
be called in the context of the function.  The information is not stored
in the active environment, you'll need to save more than that.  I think
sys.calls() will give you the information you need.
