ELF file consists of several object files, what part in ELF comes from what ELF file?

No - this kind of information is not stored in the file.  In fact the
only simple way to extract this information is to create a map file
when linking the object files together.  (See the linker's -M
option).

The only other way to reconstruct the information would be to perform
a binary pattern match between the linked ELF executable and the
various object files, taking into account the transformations that are
performed by the relocs.
