The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
No, fluorine is a diatomic gas at standard temperature and pressure (STP), meaning it exists as F2 molecules, not as single F atoms.

At standard temperature and pressure (STP), aluminum bromide exists as a solid.
Argon is a gas at STP. It becomes a liquid below -186oC and solid below -190oC at StP
A gas at STP.
At standard temperature and pressure (STP), the element that is malleable and a good conductor of electricity is copper.
Bromine is a chemical element and a liquid at room temperature, so it can be a solution when dissolved in a solvent like water or organic solvents. It is commonly used as a reagent in chemical reactions and as a disinfectant.
