Yes, an empty can is considered to be full of air since air occupies the space inside the can. Even though there may not be any other substance in the can, it is still filled with air.
Yes, a balloon full of air will weigh more than an empty balloon because the air inside adds mass to the overall weight.
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.

Yes, a full fridge takes longer to cool than an empty one because the items inside the fridge absorb some of the cold air, making it harder for the fridge to reach and maintain the desired temperature.

Any 'empty' container is really full of air, so you don't have to do anything. Pick up a test tube. It's full of air.

An empty glass full of
Full-Empty was created in 1994.
Exactly the same -
occupiedFull, occupied, overflowing...
Empty
half empty
Because the air that is in the full box is being pushed while the other box that is empty has no air at all for it to be heavy.
Take the second and the fourth full glass, and empty the contents into the second and fourth empty glass. Put the now-empty glasses back where they were. Now the glasses alternate between full, empty, full, empty, full, empty, full, empty, full, and empty.
