Well, honey, technically speaking, you don't need a hyphen for "hand deliver." It's considered a closed compound word, but some style guides might prefer it with a hyphen for clarity. So, do whatever tickles your fancy, darling.
It does not need to have a hyphen! :)
Yes.
No it doesn't require a hyphen.

I do not believe that multitasking is supposed to have a hyphen.
You typically need only capitalize after sentence-ending punctuation, which a hyphen is not.
That would depend on the way it is used in the context of a sentence. Take the following 2 sentences:We have 10 of those components on hand.This list shows on-hand hardware available in inventory.In the second sentence, on-hand is used as an adjective describing the hardware, therefore it would need a hyphen. In the first sentence, on hand is noun because it is a state of the word components.
no
