Angle of repose is equal to angle of friction.

0 to 90
Yes, they do. And this angle of repose will be different for different materials, the particle sizes and the moisture content.
None of them.
a right angle is half of a straight angle
yes, angle of friction is equal to angle of repose.
The angle of friction refers to the maximum angle at which an object can rest on a surface without sliding, while the angle of repose is the maximum angle at which a pile of granular material remains stable without collapsing or sliding. The angle of friction is specific to an object on a surface, while the angle of repose is more related to the stability of a pile of material.

It is the Emptying Angle of Repose that is greater than the Filling Angle of Repose. It is always the greater of the two Angles of Repose.
Friction angle or also known as angle of repose of soil is the subtended angle formed between the side slope with the vertical of a loose heap of the soil. This can also be determined by the triaxial shear test on soil conducted in laboratory.
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.
The three characteristics of a material that affect its angle of repose are particle size, shape, and surface roughness. Finer particles tend to have a lower angle of repose than coarser particles. Irregularly shaped particles may have a higher angle of repose compared to spherical particles. Lastly, materials with rough surfaces tend to have a higher angle of repose due to increased interlocking between particles.
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.
Water can decrease the angle of repose of soil by reducing the friction between soil particles, making them more likely to slide over one another. This can lead to soil instability and increased risk of landslides or erosion.
