About the Chara part:

When they say "Give me your SOUL", I believe they are saying the same thing: "Give me the human's SOUL". The reason I think this is because you control Frisk's SOUL, so it's possible Chara might believe it's your SOUL. Either that, or they're saying to give Frisk's SOUL which belongs too you.

About the Alphys part:

During a phone call with Papyrus and Sans, Papyrus will thing that a Labratory has dogs in it. Sans responds "I wouldn't rule it out" while winking. It's most likely a reference to the Amalgamates. This would mean that Sans could've worked with Alphys on the DT projects.

And fine, you won with Alphys. I'll label it "Speculation."
