Giving a hand up is to offer help. A hand out is a gift to the needy. A hand me down is getting my siblings clothes as I get to be their size.

A hand off is a transfer and it implies being helpful about it. A hand over, on the other hand, is more like just giving something to another, as in ‘hand it over’.

A hand over involves both the giver and receiver. Both have responsibility to have it go well. If I hand over the reins of my present job and don’t tell you all that is involved or withhold tips or knowledge of various nuances, etc, I have not done a good hand over. Similarly, if I am the receiver and I don’t pay much attention or rush or ignore your comments, that too is not a good handover
