Yes, by the weight of the helium in it. Assuming it is not in free fall, ie, weightlessness.

Yes because Helium as supplied in bottles for blowing up balloons, for example, is compressed 200 times. Helium that compressed is heavier than uncompressed air so even if the empty bottle had air in it, it would be heavier when completely full of pressurised helium.

If the helium is under pressure in the bottle it could be heavier than when under normal atmospheric conditions and full with air. If it is full of helium and at the same pressure as the surrounding air it will be lighter than if it was full of air at the same pressure.

Full of helium? Well it would weigh less than a bottle filled with air but more than a completely empty bottle.

If the bottle has air in it prior to being filled with He, then the bottle will be lighter. He is less dense than air so a given volume will weight less. If the bottle is really empty, i.e., it has a vacuum in it, then putting He in will increase the weight.

yes helium bottle is heavier when it is full.

as apposed to a normal bottle with nothing in it or with oxygen in it
it is heavier than one with nothing in it but lighter than one with oxygen in it
