I want to rotate custom figures by using graphics.rotate(...), without changing any bounds. But after rotation the figures are clipped wrong. Can so. help please.

In general, Figure does not handle rotations properly. You will have to overwrite paintClientArea() and probably also paintChildren() to address the clipping issue. Be aware that there are other implications as well. The figure's bounds will also not be correct unless you adjust them properly. There is a proposed contribution related to a rotated rectangle (https://bugs.eclipse.org/bugs/show_bug.cgi?id=117012). Maybe that can give you a start.

If you have just started to use GEF, I would recommend to use GEF4 instead. There, such kind of things are pretty easily achieved (actually they work out of the box).
