さえ also means 'even' but stresses a minimal or extreme example ('even a child could do it'), whereas も with a large number stresses surprising quantity ('as many as 100').
も is a particle meaning 'also' or 'too' attached to a noun, while また is an adverb/conjunction meaning 'also' or 'again' and can start a clause.
も can mean "even" in a mild, everyday way, whereas すら emphasizes an unexpectedly extreme case, often in negative contexts.
でも is a conjunction/particle meaning 'but' or, after a noun, 'even', while も is the plain additive particle that attaches directly to nouns or the te-form (〜ても) to mean 'also' or 'even if'.
もう is the full adverb meaning 'already' or 'more', while も in casual speech is sometimes heard as a clipped form of もう but is otherwise a completely different particle.
は often sets up a contrast between two things, whereas も says the same thing applies equally, without contrast.
Kana-only particle; no kanji spelling exists.
Native Japanese particle. The adverbial use is a colloquial shortening of もう.
