Yes, some systems use multiple page tables. On the VAX, e.g., each process has three page tables.

how many page tables are there

Entirely system specific

how many page directories

Entirely system specific. Some systems do not even use page directories.

how many [] pages

Add the page size to the process size and divide by the page size.
