The best way to compare solid materials for knife handles/scales would be to look at Specific Gravity. Specific Gravity is a way of comparing how much heavier a material is than an equal volume of water at a specified temperature.
Micarta in almost all forms will come in the lightest with Paper, Linen and Canvas ranging from 1.3 to 1.4 in that order.
Carbon Fiber falls in between Micarta and G10, but usually much closer to G10. CF can range from 1.6 to 1.7 with values nearer to 1.7 most common in the formulations used in knife handles. Keep in mind that much knife "carbon fiber" is really G10 with a CF skin on the surface.
G10 is a fairly specific formulation coming in at 1.8 in most variations.
Bone/Stag/Horn is hard to quantify. Being organic, there's a lot of variation from sample to sample. I've handled some bone scales that seemed light as a feather and others that were dense and heavy. Bone density can vary by age, gender, species and part of the body it came from. That's why when choosing a bone handled knife, it really helps to feel it in hand before buying.
As a point of reference Aluminum is around 2.7, Titanium is around 4.4 and Steel is around 7.7.
That being said the real world difference between Micarta, CF and G10 is so slight that they'd be hard to tell apart in practice. Liners, frame and blade make up such a large percentage of the weight of a knife that it's hard for the lightweight scale materials to have much impact on the overall bulk of a knife.
