The pdfedit tool can be used to do roughly that, but you still need to
know a bit about the internals of PDF files: Pdfedit allows you to
navigate the document tree of the PDF, so you can go to Pages >
$PAGENUMBER > Dictionary > Resources > Font. This will show you a list
of all the fonts used on that page; however, the names will be
meaningless internal designations like "F5". You can further expand any
such font entry to find its FontDescriptor, which (finally!) shows you
font properties like FontName, FontWeight, ItalicAngle, etc.
You can also mark a passage of text to see the associated Tf operators,
which will tell you the internal name of the font, but then you still
have to find out the real name by looking at the Resources of the page
as described above.
