Re: objects contained in a datafile

For tables and indexes (similarly for LOB segment and LOB index),

select segment_name, file_id, block_id, blocks from dba_extents where segment_type = 'TABLE' and file_id = &fid select segment_name, file_id, block_id, blocks from dba_extents where segment_type = 'INDEX' and file_id = &fid

For other objects, their definition is in SYSTEM tablespace and there's no way to know which of the multiple SYSTEM datafiles (if multiple) contains it. The size definition becomes fuzzy. But you can look at dba_object_size. (Note that this view takes a while to return anything)
