There would be an infinite number of possible sizes.
Countries all over the world, past and present, have been producing coins for thousands of years. There would be millions of different types of coins.
cuz one size and shape would be boring
nothing would happen
Assuming that you are referring to US coins, it does not seem to be possible, even if obsolete denominations are allowed, to use five different denominations of coins to make exactly 50 cents. I am not aware of any other countries that use "cents" that would allow you to do so either. However, in Czarist Russia, and in the Soviet Union, there were coins in the denominations (among others) of 2, 3, 10, 15 and 20 kopeks, the total of which 5 coins would be 50 kopeks.

Coins come in different sizes and weights. You need to specify more clearly a coin. I assume that two coins in the question means a two pence piece? The weight of a two pence piece UK is 7.12g. Therefore: 7.12 x 100 = 712g
They would not be released. There are to many quaility assurance checks for this to ever occure. If it did happen, the coins would be melted down, like what happens to old coins and damaged coins.
The answer would depend on their relative sizes and the food pyramid.

No, not all coins weigh the same. The weight of a coin depends on its material composition, size, and denomination. For example, a nickel weighs more than a penny because it is made of a different metal.
To be able to deal with different sizes of cash purchases. Buying expensive stuff with only small mone would mean that you had to carry a lot around. Buying inexpensive stuff with only big money around would mean that you'd get a bucket of coins in change every time.
At one time coins contained metal that was worth as much as the denomination of the coin, minus a small profit for the government or agency that made the coins. For example, old US cents contained a cent's worth of copper, dimes had 10¢ worth of silver, a quarter-eagle had $2.50 worth of gold, and so on.Because different metals have different values, the coins' sizes were determined by the value of the particular metal they were composed of. That's why, for example, that pennies are larger than dimes - when the penny was copper and the dime was silver, silver was much more valuable so it took less silver to be worth 10 cents than it took copper to be worth 1 cent.However, within each type of coin, sizes were proportional. For instance, a half-dollar was twice the weight of a quarter, and a dollar was 10 times the weight of a dime.When the US took silver out of its coins in the 1960s there was no longer any financial reason to keep coin sizes in proportion, but there were so many vending machines and coin sorters in use that the Mint didn't even consider changing sizes - it would have been too expensive to retrofit all that equipment.However, when new coins are introduced or a country changes its coinage, proportional sizes are generally no longer used except in certain cases. That's why the new US $1 coins are smaller than half-dollars. And in the EU, where all old coins were replaced in 2002, sizes were chosen for convenience and logic rather than proportionality.
The seasonal variations would be different.
Using standard American coins (1, 5, 10, 25 cents), the fewest number of coins to make $0.13 would be four -- one dime and three pennies. This number would be different in countries that use different denomination coins, such as the 2-cent piece.
