No, glycogen granules are not membranous organelles. They are non-membrane-bound structures composed of glycogen, a polysaccharide that serves as a form of energy storage in cells. Glycogen granules are found in the cytoplasm of cells, particularly in liver and muscle tissues, and are involved in the regulation of glucose availability.
No, they do not. Only animal cells have glycogen granule to store energy.

Glycogen is a large, branched polysaccharide that appears as granules in cells. Under a microscope, glycogen granules can look like small, irregularly shaped particles. In electron micrographs, glycogen appears as densely packed clusters within cells.
Organelle A double membranous organelle. It can self replicate.It is like a power house
Glycogen granules form an energy or food store in mammalian cells. When needed, the glycogen can be broken down (hydrolysed) into glucose, which is used in respiration as a source of energy for the cell. For some background see: http://www.sciencedaily.com/articles/g/glycogen.htm
The organelle responsible for converting glucose into glycogen is the smooth endoplasmic reticulum (SER).SER is involved in glycogen synthesis in liver and muscle cells by synthesizing and storing glycogen granules in response to insulin signaling.
Mitochondria
Ribosomes.
No, they do not. Only animal cells have glycogen granule to store energy.
No, they are simple storage molecules.
Glycogen is stored inside a cell in the form of granules in the cytoplasm.

Cell CytoplasmThe cell cytoplasm contains various other substances and structures, including stored foods (glycogen granules and lipid droplets), pigment granules, crystals of various types, water vacuoles, and ingested foreign materials.Human A&P Lab. Manual -9th edition [cat version] Mariebpg. 44
Glycogen is stored in the liver and muscles in the form of granules or crystals. These granules act as a readily available energy source for the body. As for pigment, it is a substance that can give color to tissues or structures, but it is not directly related to glycogen storage.
