Try not to invite Aretha Franklin and Queen Latifah over for dinner and your floors should hold up just fine.
That depends on how well supported the floor is and that depends on how far apart the joists are placed. The closer they are, the more weight can be supported.
as much as ceramic or porcelain tiles
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
depends on length
I don't know but I would like to know. Get a life.

That depends upon the size of the joists & grade/species of wood
all depends how the floor is constructed and the size of the joists, the span of the joists, thickness of floorboards. Is it a concrete floor. Is it a 'live' load like people of furniture or a 'dead' load like an unsupported wall. It the house an old building or of recent construction. A residential standard suggests 40lb per square foot. Needs confirmation though
That depends on the sise and the type of timber the floor boards are made of, However standard practice with flooring is 450mm centers or 600mm centers if the boards are thicker to allow for the extra 150 millimeter's
It will hold more weight than you can ever put into it !- My floor joists are 2x10 at 16 inch intervals, and I installed a 48 x 60 spa tub that holds about 20 cubic feet of water, that weighs around 1200 pounds. Include two average people in it and you have over 1,500 pounds ! - The floor holds just fine .

It depends on what timber your joists are,how much water has been involved and for how long the water has been affecting the joists.Stop the egress of water and let the joists dry out.Take it from there.
That depends on (a) the mass of amount of pressure applied by the tonne - how much area does it occupy and (b) the strength of the joists - the boards the floorboards are laid across. it also might depend on whether the floor is at ground level or not.
You put how much you think it would hold and if it collapses, then you know for next time that it can't hold that much.
Typically you would not put hardwood flooring directly over the joists. You should first put down a subfloor.
it can't hold very much weight
When you stand on a floor, the force that you exert on the floor because of your weight is equal to the force with which the floor supports your weight.
