Cannot be determined as for some test shots the testing nation still considers the type to be classified information. And with underground testing nobody else can determinee type by fallout isotope tests.
A nuclear bomb can be made with any desired yield from about 10 tons to well over 50 megatons in one single bomb. These numbers are just for tested devices that worked, there is no theoretical upper limit on the yield of fusion based bombs.
Because its been tested many times, and never failed the test.
Both words are technically interchangeable, so your question cannot be answered as written. Perhaps you meant which is bigger fission or fusion bomb? Define bigger: size or yield? The biggest bombs ever built in both size and yield have been fusion. But many modern fission bombs are bigger physically than fusion bombs with bigger yield and some fission bombs have bigger yield than some fusion bombs. Confused? It all depends on purpose.
There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.
Question as written cannot be answered as it depends on very many unspecified variables, the most important being the yield of the bomb which with already tested bombs can vary from as little as 10 tons TNT equivalent to over 50 million tons TNT equivalent.
Several thousand, mostly by the US and USSR.
No nuclear bombs were tested on Easter Island.
"Millions of hydrogen bombs"

There first ones were Uranium gun assembly fission and Plutonium implosion assembly fission types. Then came the Hydrogen radiation transport driven implosionthermonuclear bomb.There are now many additional types including fusion boosted fission bombs, enhanced fallout and reduced fallout bombs, neutron bombs, etc. Many of which although they have been designed have never been militarized and stockpiled by any country.But all can be called atom bombs or nuclear bombs.
About 2,000 animals have been tested in Toronto.
More than a thousand in total. Only one was tested during WW2.
In all nations, several thousand- the exact number is not pulic information. 982 were tested at the Nevada Test Site alone.
Two.
Out four H bombs lost in spain three have been recoverd.
