This kind of reeks like a begin/end date and an accuracy quantifier,
though that wouldn't account for option 6.

Your cases 0 to 5 and 7 would be transformed into something like:

    date A    date B     accuracy
0: NULL      date1      5
1: date1     date1      3
2: date1     date1      2   (is 'ca.' less accurate than 'say'?)
3: date1     date1      5
4: date1     NULL       5
5: date1     date2      2
7: date1     date2      5

Where I defined '5' as being accurate, and lower values less accurate.
You may want to use values with a wider spread, it'll allow more
fuzziness about how sure you are about a certain date.

Just my 2 centims.
