No.1
"in sb's hand" and "in sb's hands"
According to my dictionary:
be in hand: if a plan or a situation is in hand, it is being dealt with
The arrangements for the party are all in hand so we don't need to worry about that.
be in sb's hands (in my textbook it is "hand"):to be dealt with or controlled by someone
The arrangements for the party are now in Tim's hands.
Does it mean the two are interchangeable? If not could you please explain if there are any differences between the two?
They are similar in meaning, but they are not interchangeable, as your examples show. the first is more general. In the second you are talking about a specific person.

The textbook adds "off hand" in the blank but I think it should be "in hand". Is that right?
No. It should be on hand. The expression is cash on hand.

Moving to London is certainly a possibility. I wouldn't dismiss it out of hand.
It seems the phrase means "completely". But in another dictionary there is the sentence "Please wait a minute, I'll go with you out of hand", in which the phrase means "immediately". So what does the phrase mean?
If you reject something out of hand you do so without even bothering to think about it.

off sb's hands: if someone or something is off someone's hands, they are not responsible for them any more
I've got a lot of freedom now the kids are off my hands.
be out of sb's hands: if a problem or decision is out of someone's hands, they are not responsible for it any more
The court will decide how much money you get - the decision is out of our hands.
To me the only difference between the two is that the first one can refer to both people and something while the second one can only refer to something. Does it mean if I refer to something both are correct?
Generally speaking:A person or persons is off your hands. Example: "Now that the kids have left the house they are off my hands."
A decision or responsibility is out of your hands. Example: "Now that I have resigned, that decision is out of my hands."

Could you please explain the difference between "an odd job" and "odd jobs"?
I think the first one mean "only one job" while the second one means " more than one oddjobs" Is that right? If it is does the first one mean a job done at irregular time?
