With the macro lenses is quite difficult to go wrong, all of them are very sharp but slow focussing and of course they can be used for portraiture as well.
The best value for money is the Tamron 90mm, a lens that is slightly sharper than the Nikon 105mm (both the D and the VR) and has the best bookeh of all macro lenses, but the one that should be chosen is the "272ENII" type since that one has an internal motor so that your D5200 will AF. The last version has VR, more precisely VC as they call it, but then is more expensive.
The next one might be the Tokina 100mm, good construction good quality of image.
Then there is the Sigma 105, but Sigma always had some issues with quality control... but sigma when is good is really good.
Now the Nikon 105 VR has the newest optics. VR is not a deal breaker since at 1:1 VR is useless.
So if budget is not an issue then the Nikon 105 VR, but if not you might consider the Tamron.
