Yes. The Universe is expanding.
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
As the universe expands, the density of galaxies decreases. This is because the space between galaxies increases as the universe expands, leading to a lower concentration of galaxies in a given volume of space.

No
Percentage change in volume= Change in volume/intial volume X 100
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
Honestly, the universe is a pretty big place. No one really knows the volume of aluminum as a percentage of the universe.
This is volume of the Universe ! As an unit of measure the cubic metre and multiples.

The volume of the universe is not precisely known, as it is constantly expanding. Scientists estimate the volume by measuring the observable universe's size and extrapolating it to the entire universe. This calculation involves complex mathematical models and data from observations of cosmic microwave background radiation.
No it doesn't change its volume
it cannot change its volume because it has a definite shape and the electrons are tightly packed but it can change its volume when there is a slight change in temperature.
