Ok. We do see Chara narrating in red text during parts of the Genocide run.

I do agree that Sans Papyrus and Gaster traveled together from another place, and know each other well. Papyrus is definitley a real skeleton monster, but my own take is that Sans and Gaster were both human, at least at some point in the past.

If Flowey actually had a monster soul and a human soul, he'd be able to go through the barrier on his own to collect more human souls, and wouldn't need to hunt for Asgore's 6 captured souls. It's possible he never tried to go back through the barrier, believing himself to be empty, but with all his Groundhog Day resets I think he'd of discovered it eventually. I don't think anyone succeeded in going through the barrier except for Asriel and Chara until the barrier was finally destroyed.

Ghosts definitley have a very important place in Undertale. We know Mettaton used to be a ghost, and Blooky's cousin, so ghosts have souls. Blooky also says in the True Pacifist Epilogue that the white light that was collecting everyone (Asriel) tried to collect him too, but he closed the blinds, and afterwards he was the only one who couldn't remember who Asriel was. Ghosts and burrowing creatures (like Flowey) are specifically listed as the only creatures who can travel back and forth been the Underground and The Ruins, which Blooky can certanly do.

Ghosts and Amalgamates also seem to be the only creatures who can radicatlly shift their shape. Which is very interesting, because Muffet says she saw the creature who paid her to collect Frisk's soul shapeshift in the shadows. A ghost might have it in for Frisk.

Chara is a ghost, and is called in many places in the game Neither Human Nor Monster, able to absorb human and monster souls. A first-class threat.

In Gaster's secret room, you can walk right through his sprite as if it isn't even there, something you can't do with most NPCS. Then he shapeshifts a little as he fades away when you touch him. Gaster's definitely a ghost now, and he's going to be incredibly dangerous in the next game.
