Answer 1

Placeholders are boxes with dotted or hatched boreders that are on most slide layouts. They hold things like title, body text, table and graphs.

Five are quite easy:
Title placemarker
Object area placemarker
Date placemarker
Footer placemarker
Number placemarker

you could also text placemarker (which is a subset of object placemarker)

Answer 2

sorry - clearly I meant placeholder rather than placemarker.
