From my understanding yameen refers to during in the past e.g. wallahi fulan did such and such, but nadhr refers to the future e.g. wallahi I will do such and such, but I am also confused. Can you write the definition of both if possible??

This is not correct.
Yameen is an oath whether in the future or the present or the past.
Nathr is a vow or a pledge and one says it to obligate it upon himself to do a certain form or worship.
