First, I'm assuming the real Sephiroth was killed at Nibelheim?
Yes. No matter what way you look at it - Sephiroth died when he fell into the reactor. That's that. His will was carried through because he took JENOVA with him + the cells in his body. Had he not fallen with JENOVA's head with him, things would've probably been considerably better.

"Does the "real" one ever return?"
- Nope. It's all JENOVA and Sephiroth's will I'm afraid. If you have ever looked into what Aerith's mother says to Professor Gast in the Icicle Lodge - she speaks about a creature/Calamity that fell from the skies. It morphed as one of the Ancients, appeared to help them, decieved them and made them ill killing a lot of them off. It required a great effort by the Ancients to seal JENOVA at the Northern Crater. When Shin-Ra dig it up, it worsens everything.

If not, who is the Sephiroth at the end of FF7 and in Advent Children (no I didn't watch that yet either)?
- Sephiroth at the end of FFVII is a mutated corpse of the body that fell from the reactor. His body had been enhanced due to the effects the Lifestream had on it, and JENOVA was able to channel that energy in such a way. Sephiroth is DEAD. D-E-A-D. There are no two ways about it. But because he was a willing catalyst for taking JENOVA to a point of being able to cast Meteor - his will was emulated by JENOVA - just like it did with the Ancients before. I can also prove this further with what Sephiroth says at the temple of the Ancients. He states that he wants to wound the planet - and stand at the centre of the wound, to become a some sort of God-like creature.
But if you rewind to when you find him in the Shin-Ra Mansion Basement - you'll see that he talks about serving 'Mother' - JENOVA. He states nothing of this after his death - and instead talks more about ruling the planet by himself - almost as if his 'Mother' wasn't important. This is also why parts of JENOVA fly off Sephiroth when you see him in game. It's arm becomes a manifestation that you have to destroy on the Shin-Ra Cargo Boat.
The Sephiroth at the end of AC is the body of Kadaj playing host to JENOVA's shape-shifting ability and of course - a part of Kadaj's and Sephiroth's will also helps JENOVA manage to manipulate them properly. Kadaj dies of course at the end.

Were there any Sephiroth "clones" that were actually clones i.e. looked like him?
- None. Not exact look-alikes anyway. 'Clones' was a bad word for Hojo to use. Remnants is better. You find a man with a numbered tatoo in the Sector 6 Slums. He can't speak, or do shit except for go "oooo. aaaaaaah". Red XIII is another experiment of Hojo's - only this time using a rare species. But the experiment was still the same.

If the real one never comes back, is he up in the lifestream somewhere?
- He was in the Lifestream - and ended up at the Northern Crater, crystalised in Mako, garnering power from the stream. But he's still dead remember - it's just his corpse. You destroy his corpse when you defeat him in his One-Winged form. So after the original game is over - Sephiroth's body is DONE. The original is no more.
So people will then try to contradict this by saying, "Wait a minute - Sephiroth appears in the game. If he's crystalised in Mako at the Northern Crater, how can you see him at other points in the game prior to discovering him there?"
Because that's not Sephiroth - it's JENOVA. JENOVA can morph to take shape of things. It's how the character you trust with the Black Materia at the Northern Crater get's tricked into going to hand over the materia to Cloud - (usually by shape-shifting into Tifa or Barrett, or whoever depending on how you entrusted this task to).
Also - the reason why JENOVA can do all these things is because it escaped from it's holding in the Shin-Ra building. Dragging its deformed, alien carcass everywhere - clawing at the walls and the floor when you're following the trail of blood to President Shin-Ra's office.

Thanks for any and all answers, and I appreciate no belittling of my lack of FF7 knowledge.
Lol - no problem and that's understandable. What you need to remember is that Cloud and co never fully figure this out themselves either. That's what makes the plot so deliciously confusing. The tragedy with Sephiroth is that he never meets his real mother. Lucrecia was kept away from Sephiroth - and because she was so driven with guilt about letting Hojo experiment on Sephiroth she went and crystalised herself in a Mako Fountain - how quaint eh?
So yeah, Sephiroth was never set out to be bad.. just reading all those books and never knowing his true Mother drove him absolutely mental.
Feel free to flame me if you disagree with anything I've said - I won't care for your response.
However if you want to be civil and debate any points I've made here in a civilised manner - feel free. It's all up to interpretation apparently - but IMO, that's how it happened and how it was written originally.
