He probably knew 2 or 3 Elven languages (the native Mirkwood elf language, Sindarin, and likely some Quenya that he learned back in school), and at least the common language of the humans. It is highly likely Gimli taught him the dwarven language after the story ended.
However, as Elrond (and, of course, Elros) were raised by Maglor, but were born in Middle-Earth, would they speak Sindarin or Quenya? They might have spoken both. Having been born at the Havens of Sirion, they most likely spoke Sindarin as their birth tongue.
