At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
Mercury has the highest density in this series.
Mercury is the only liquid metal. Bromine comes under group 7 in the table and is therefore a Halogen. Bare in mind that this is only true at standard states.
Mercury is an element and therefore a pure substance.

No, mercury has a very high density.
Aluminum is the lighter than mercury.

Yes, mercury can dissolve Aluminium by forming an amalgam.
Mercury is the only liquid metal. Bromine comes under group 7 in the table and is therefore a Halogen. Bare in mind that this is only true at standard states.
There is a chemical reaction between mercury and aluminum, forming what is known as an amalgam.
Aluminium will always float in Mercury. The mass of the Aluminium is irrelevent. If you think of a more common example does it matter how big the piece of wood is as to whether it floats in water? Aluminium floats in Mercury because it is lighter than the same voluime of Mercury just as wood floats on water because it is lighter than same volume of water.
Mercury is the lightest planet, with a mass of 0.055 that of Earth.
Mercury is a pure substance, more specifically it is an element.
If Mercury (element) is heated then like every other substance it expands.
Mercury is an element and therefore a pure substance.
