I have a 2 story home and want to add a bathroon (exhaust) vent to the
bathroom on the 1st floor. I need to get some advice on whether this
is do-able or not. And if so how? I'm sure every scenario is different
but a general idea would help.

Well, I doubt that you want to pump it into the bedroom
upstairs (unless it is a guest/mother-in-law room) so
you will have to find a common wall to get it to the
attic or go out the side. Either way isn't choice but
that is your only 2 options. Unless you can pump it
into a crawl space below the bathroom.
They make wall mounted fans that will dump through the
wall and from your description, that is really your
only option. Also through the ceiling joists and out
Cut a hole in the outside wall, run wire to it, run a
timer switch to it. Really, is it worth it???? I
don't think so either.

Years ago you cut a hole in the window glass and fitted a fan in that. This
isn't possible these days as the windows use sealed double glazed units. You
can howver buy extractor fans designed to extract through a hole in the
wall.
In the UK something like this range

Run a vent up to the attic via the wall if workable. Don't know your floor
plan in relation to 1st floor and 2nd floor.
Opening a window after/during the shower/bath may work as well. If no
window, forgive my assumption.

First, this is very do-able. Second, you must vent directly to the
outside, whether you vent through the attic or wall, to meet today's
code requirements.
(IRC Section M1501.1 Outdoor discharge. The air removed by every
mechanical exhaust system shall be discharged to the outdoors. Air
shall not be exhausted into an attic, soffit, ridge vent or crawl
space.)
If you choose the floor/ceiling space method (which I would
recommend). First you must determine the direction of floor/ceiling
joist and the distance of the run. Then check the distance of run vs.
the fan mfg. requirements. then install per mfg. requirements.
If you choose the roof vent option. First you must determine the wall
position on the floor above so that you can locate the fan close to
that wall. Then you must open the ceiling of the bathroom and the
wall of the floor above to cut through the top and bottom plates (If
this is a bearing wall additional steps may be needed). Then you must
make a penetration in the roof assembly according to the roofing
manufacturers requirements. Then install the fan and duct per mfg.
requirements.
As you see, the first option is less intrusive and requires fewer
repairs to the interior finish.
Hope this helps!
