The question is not clear enough to answer completely. Why are other peoples "goods" on your property? Do you own a warehouse? A storage facility? Do you offer storage to these people for their goods? Or, did the goods just "happen" to coincidentally be there in the wrong place at the wrong time? In the first instances - you should have had insurance to cover the eventuality of theft. In the last case, your homeowners or business insurance should cover it.
Homeowners insurance policies are personal lines coverage and typically do not provide coverage for commercial or work related activities.
Larceny is stealing someone elses property, so your answer is stealing firearms
You home owners liability insurance should cover it.
That depends on the law of your state.
In my opinion Should your policy include liability to other people the policy should make allowances too cover any claim which may arise at your property due to negligence on your side, however if one cannot prove that there is negligence you cannot be held liable. You would also need to consider the type of cover and whether the damage woudl fall within the ambit of your policy
Propety Damage covers you if you damage someone elses property. Liability covers you in the event of a lawsuit.
