Human
Hot chocolate
Whale
Chicken Curry
An Apple
A pint of Guiness
A strand of hair
A snail
A rhino
Ketchup
These are all identical when it comes to composition. Basically C, H, O, N, P, S, Cl, Na, K, Ca, Mg plus some trace elements.
iPad
Humvee
motorbike
A satellite
Again, not much differences between these objects when it comes to elemental composition. Relative amounts of elements will vary, but they will also vary between satellite and satellite (they are not identical), between different motorbikes, or even between "dry" humvee and the one that is filled up and ready to go.
The Pyramids
Bathroom Tile
Basically the same thing.
Lightning
Hardly an object, more like physical phenomenon, doesn't have an elemental composition at all.
I think you already owe me at least $50
