Nobody has ever had enough bombs to blow up the earth! The figure that there are enough nuclear weapons to kill everybody on the earth 10, 20, 50, or however many times over is an entirely different issue (and is very speculative). It may have been true in the middle 1980s at the peak of the arms race, but since START was signed total number of weapons have fallen continuously.
Earth has a gravitational binding energy of about 2.5* 10^32 Joules. This is the absolute minimum amount of energy needed to destroy the planet. While the Hiroshima bomb release about 6.7*10^13 Joules. So it would take at least 3.7*10^18 or about 3.7 quintillion Hiroshima bombs to completely destroy the planet.
Cannot be answered as it depends on too many variables:
If by destroy you mean blow it up, more than we can get.
Excluding tests 2 they where on the Japanese cities Hiroshima and Nagasaki in 1945 6 august and 9 august to end the war and 2 days later Japan surrendered
To blow up all of it would take thousands of them.
100000000
OVER 9000
Out four H bombs lost in spain three have been recoverd.
You can count them yourself in the related link on The Nuclear Weapon ArchiveA Guide to Nuclear Weapons
Depends on yield and height/depth of burst.
none The only "nuclear war" ever fought was in August 1945 when the US dropped two atomic bombs on Japan. Japan had no atomic bombs so all they could do was surrender. It was rather "one sided" and it ended WW2.
Nuclear bombs were used against human kind in Japan's Hiroshima and Nagasaki cities. It killed humans of every age, horses, dogs, cats, rats and mice. It also killed insects as roaches, ants, fleas, ticks, flies and roaches. A myth was spread that roaches don't die in a nuclear blast. That is not true.
It would depend on the size of the bomb.

Cannot be answered as there are too many variables, only one of which is the yield of the bombs used.
that would depend on yield and where they were detonated. but the answer is more than have ever been built or could be built.
Do you mean - to kill everybody, or - to make the Earth disintegrate? It also depends on how big the bombs are and where they are placed.
To say how many nuclear bombs it would take to blow up the sun is almost impossible. Actually the sun is a continuously exploding thermonuclear bomb, that's where the energy comes from - fusion. It doesn't matter how many bombs you shot into the sun, it would just get hotter.
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
No nuclear bombs were tested on Easter Island.
Anywhere from 1 to trillions, depending on:yieldburst height/depthburst slant rangeetc.
none, australia is not a nuclear power
Well, to my research there hasn't been any nuclear bombs, Aussie has built.
About 10700000000000000000000000 h bombsThis is a complicated function of:yieldslocations of burstsmaterial around burstsetc.It would be far far easier to just blow away the atmosphere and leave the earth alone and even far far easier to light firestorms in all the forests and fill the stratosphere with soot for decades causing nuclear winter.
