How many endings are there? So far I've gotten the solo endings (normal, drug dealer, stripper, escort, wedding rings, actor) and the Annabell corruption endings (travel agent and cinematographer)

Those are all the current endings apart from bad endings and the two joke endings (Lottery and the Long Lost Father ending). The former has a 1 in 250 chance of triggering, whereas the Long Lost Father requires some rather specific things and to stumble upon the 'father' event at the Pink Lounge. Neither of these unlock any items.
Also, not a specific ending, but if you go down Russ' path and learn to drive stick, you can unlock the Futo NT-R Model, which allows you to buy the Futo NT-R car ($2000 instead of $3000) on any playthrough.
