uhh... take the chord (arpeggios are chords) find another chord that harmonizes with it, and either arpeggiate it and play that at the same time or move the arpeggio your playing up/down the neck (because its like a barre chord and that works that way lol)

no different than harmonizing anything else really... the synchronization is probably much more difficult.

Minor harmonizes with major two steps up.. vice versa

like an A minor chord would "harmonize" (spelling LOL) with an C major chord??
Yes if you want to harmonize in minor thirds.
