I'm looking for medieval and renaissance guitar chords and tabs to learn any suggestions... like renn music.. no.metal and such
Harmonic minors will give you that Persian/wicked sound (I'm going somewhere with this) so during the renaissance times the church outlawed the harmonic minor because they said the augmented second was too demonic, so most true ren times music used majors and melodic minors.
D Ionian, G Ionian, A Dorian and E Dorian scales
All major chords and minors, and then throw in some majors with flat 7ths to give it a Celtic vibe. Reels and Jigs are always fitting.
If you are feeling really adventurous, start exploring DADGAD tuning.

She moved through the fair
I know you said no metal, but check out eternal wait by ensiferum. I play it on my acoustic all the time with a more chantey sound.
Oh yeah! also The Drunken Scotsmen.
