Your D3200 won't meter with old Nikon AI lenses, you're going to need something on the higher end in the DX00, D7X00 range. Basically, if it's a Nikon DSLR and it has the little ring and tab around the mount pictured here near the top right screw on the mount, it will work with old Nikon AI lenses.
You will not be able to adapt Canon lenses to Nikon's mount, because of the flange focal distance. Nikon's F mount is further from the focal plane than every other common system, so you're pretty much out of luck.
This stuff is available on wikipedia, just search flange focal distance:
Nikon F - 46.5mm
Pentax K - 45.46mm
M42 - 45.46mm
Minolta A - 44.5mm
Canon EF - 44mm
Fuji X - 43.5mm
Minolta SR - 43.5mm
Canon FD - 42mm
The only way to adapt a lens from a system with a smaller flange focal distance than the camera it is going on, and retain infinity focus, is to make an adapter with optics in it. If you simply machined a ring that would adapt mount-to-mount, the larger the discrepancy (lens FFD < body FFD) the more focusing ability you lose. So it would work fine for macro, but you would lose close focusing capability. That's basically how macro extension tubes work.
