The Italian is the hard part, since they aren’t exact numbers:
adagio = slow
allegro = fast
andante = moderate
grave = slow, heavy
largo = very slow, broad
lento = slow
presto = very fast
adagietto = “little adagio,” a little faster than adagio
allegretto = “little allegro,” somewhat slower than allegro
andantino = “little andante,” an ambiguous term, meaning either slightly slower than andante or slightly faster, depending on your point of view
largamente = very slowly
larghetto = “little largo,” slightly faster than very slow
meno mosso = “less moved,” slower
più mosso = “more moved,” faster
prestissimo = “very presto,” extremely fast
