OK - from my experience
Oregano prefers light sandy soil in full sun. It will tolerate cold winters once it is established, but will not survive harsh winters. In my old garden it thrived in the worst soil I had- very dry & sandy exposed to the full sun and coped with -10C in the winter. It spreads over time, and tends to grow to about 2 foot high. Anywhere that Marjoram grows well, Oregano will also grow well. Remember it is a mediterranean herb originally.
Garlic - needs much sun as well - the more the better. Soil is important with it prefering fertile soil which is well drain and not compact, so light and airy. I never really sucessfully managed to grow any decent sized garlic.
Parsley - needs full sun ideally. It needs good fertile soil and prefers (in my experience) damper soil. It needs water to prevent it running to seed. It is also a biennial which is one that takes 2 years to flower & seed. In the right soil & condition I have seen it grow to more than 5 foot tall!
Rosemary is reasonably easy to grow assuming that you don't have an excess of the beetle that kills the plant. It needs a warm sheltered spot, but I have found it will grow in only partial sun, though it is meant to be a full sun herb as well. With time, rosemary bushes grow really large and also spread out a long way. Again it is a mediterranean herb, so think of those conditions, but it has surprised me, surviving snow and -10C conditions once established.
Chives & sage will pretty much grow anywhere from experience. Both tolerate full shade conditions, but prefer sunshine, but I have seen chives wilt in excessive heat & sun, so your spot sounds ideal for them.
Thyme is another really useful one to grow, if you can get hold of common thyme (I hate lemon thyme). It again prefers full sun, in well drained soil, but will handle partial shade but not freezing conditions.
All of the above will not cope well with waterlogged soil. If your soil is not well drained, you may need to add sand or other suitable material to it to assist the herbs, or grow them in pots.
