Yes, there are! You can play the three notes of the D minor chord in any order, and you will still have a D minor chord. When you change the order of the notes in the chord, this is called playing the chord in an inversion.  If you play the D minor chord with an F as the lowest note, you are playing the chord in first inversion. If you play the D minor chord with an A as the lowest note, you are playing the chord in second inversion.
