Whether you charge or not isn't relevant to your responsibilities under
OSM's license. The only relevant question for share-alike is, will you
be storing data that's derived from ours in any way? If so, that's a
derivative database and must be shared back to us.

1,3,4 sound like "produced works" and would require that you show the
OSM copyright message.
2 would be a "derivative database" if your users are placing POIs in a
certain place *because of features that appear in OSM*. For instance, if
your tiles show a road in OSM and the user places a POI next to it, then
the POI's location is derived from OSM and must be made freely available
if someone asks. After all, if you used a different base map with the
road in a different place (since all maps have errors in), the POI would
have been in a different place.
There is a wiki page which lists some more use cases at:
if there are any cases you're interested in that aren't covered there,
could you let us know? Then we'll be able to improve it.
