First one's right: 1900= nineteen hundred As for the others: 1907= "nineteen oh seven" (For some reason, we say "oh" for the zero here. You can also say "nineteen hundred and seven" but that sounds a little old fashioned) 2008= "two thousand eight" (no "and") or "twenty oh eight" 2010="two thousand ten" or "twenty ten" 2014= "two thousand fourteen" or "twenty fourteen" 2020= "two thousand twenty" or (you get the idea by this point) "twenty twenty"

Just something to add to Jeremy's very comprehensive answer: British English puts the word 'and' after 'thousand', for example 'two thousand and eight', 'two thousand and fourteen'.

Jeremy was very wise to point out that in some English speaking countries, and certainly in the United States, we do add "o" or "oh" to years like 1901, 1903, 1907, and so forth. It is obviously an error to confused the Letter of the Alphabet with Zero, but we do it anyway. Clearly, it is easier to say "o" than to say ZERO. It is wrong, but we just adopt the simpler expression. This may puzzle some students of English to know end. They may well ask "why?". It is now custom in the USA.
