No, it reuses it for each ESRIPoint.

Anything Java can handle internally. The code uses a
javax.swing.ImageIcon to load the URL of the image. Certainly gifs and
jpegs, but I think tiffs, too. png.

The AreaShapeLayer can do this, but you'll have to set the properties
for the URL for the default, and for each point with a particular
image. You could also extend the layer, and modify the code to set the
images in the points yourself.

No, it depends on the layer.

The appObject of an OMGraphic (OMGraphic.getAppObject()) contains an
Integer of the row ID.
