I would answer no.
You might be able to use a stylus for writing in a word processing program, but I doubt you could use a stylus to type text.
You might be able to use the touchscreen to select letters, but it would probably be a pain to use for typing.
If the tablet supports the stylus, yes. But it's probably not going to be a very good experience.
No.
In most cases a stylus is used with a Wacom digitizer tablet, but they're not used for typing.
