One cubic meter (~1 cubic yard) of water is one metric 1 ton, or ~2200 lbs. Plaster is heavier, my guess is about 1.5 tons. Bagster "containers" can hold up to 3300 lbs and they limit heavy debris to one cubic yard.
Stone can be measured in tons or yards. Actually yards refers to cubic yards. A cubic yard measures one yard by one yard by one yard (in feet, 3 x 3 x 3). When stone is in a pile, try to estimate the volume in cubic feet, then divide by 27 to get cubic yards.
This question cannot be answered sensibly. A cubic yard is a measure of volume, with dimensions [L3]. A ton is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. As a simple mental exercise consider a cubic yard of air and a cubic yard of water. They will have very different masses.
