If during surgery, a small portion of an organ -say liver- is severed-off and a minute later is placed back nearly as it was but not perfectly aligned to its original position; will it re-attach and function, heal and work properly or the portion will die/rot/cause trouble ?

In the case of a section of liver it should do because living donor transplants are possible where a section of liver is removed from the liver and disposed of, then a section of new liver from a donor is transplanted into the recipient and their liver will utilise it, albeit with immunotherapy as well. I think it can be extrapolated from that what you ask is possible and you wouldn't need immunotherapy because it's your own liver. I'm not sure if all the tissues are capable of this.

Neural tissue. There you have one that isn't. I'm not sure either about other tissues; the liver has highly proliferating 'stem' cells

Right.
