Tom is right, SE for the most part on location, but depends on how much canopy you have. If your shrouded in trees, then South can be safe enough. See nestwatch.org - This site is superb for figuring out *anything re *nest box. These little birds are not territorial between species, but will be with conspecifics (same species). The Nestbox site tells you approx how far away from each other you can put boxes.
Please exclude raccoons - nest boxes are basically an obvious buffet for these guys, and they can simply reach in and pull the eggs, babies or parents out. The little metal hole plates help to exclude the chipmunks and squirrels (when the hole is small). The more you check on the bird, the more of a path to the box you are creating. All your jays eat eggs to adults as well, so if you frequently go look at your box, you could find a jay perched on top one day snagging the babies as they stick their heads out for feeding.
The nest box sizes on the Nestwatch site are correct except for Tree Swallow and Bluebird (5.5 inch sq bottom for both). Metal poles place out in a meadow are great for these guys. The Tree Swallow Project has a great plan for these boxes and a load of info. For siding issues, put the box right over or near the hole. Make sure there is fir or aspen chips in them, excavators need to excavate or they may not like your box.
