Just to clarify, a wakizashi is 30-60 cm in length, with the shorter (closer to a tanto, or dagger) being referred to as ko-wakizashi, and the longer as o-wakizashi. A katana generally ranges from 60-73 cm. Honestly, the term daisho might be more fitting - a matched pair of swords, one being larger than the other - though I don't know if the two parts of Gambol Shroud can be called matched.

A kodachi is just a tachi shorter than 60 cm. A tachi is just a predecessor to the katana, and is very similar in style.

Of course, given that all of these are types of Nihonto, or Japanese swords, I think Gambol Shroud falls into none of these, since Japan does not exist in Remnant (like Germany, oh "Schnee-is-mispronounced" criers).
