You need to 'float' the selection (e.g. detach it from the source layer) before
you attempt to drag it around, otherwise, clicking and dragging will only move
the selection 'mask', not the selected contents. To float a selection you use
the "Float" command from the Select menu, or I believe the keyboard shortcut is
Ctrl+Alt+drag (the statusbar will change to read "click and drag to move
selected pixels" when you get the modifiers right).

In the Colors (or was it Layer?) menu. There is actually more than one way to
reverse 'color polarity', but it depends on what colorspace/model is being
used; the standard Invert command uses the default RGB space.

Under Image > Transform. (If you image contains multiple layers, use the Layer

Some programs you have to flatten the images into 1 image and then
proceed to select a small portion of the greater image to drag, resize,
etc to position next to the other image.
Mind your terminology. Under the Edit menu you can say "Paste As > New Image"
but then you wind up with two completely separate image windows with zero
interaction between them; you're probably asking about "paste as layer" (also
available in the Edit menu). Alternately, when layer positioning is important
you can do a regular paste, and while the selection is still floating go to the
Layer menu and select "To New Layer" which will unfloat the selection and make
it a new layer on top of the old one.
Numbers may not lie, but neither do they tell the whole truth.
