I am a novice to photography and recently purchased a D5100 with a Nikon AF-S 18-105mm f3.5-5.6 ED VR Lens. This Lens is sufficient for my needs as an all round lens however I have realised that I mostly take portraits so would like to invest in a portrait lens (on a budget).
Could someone please advise on which of these two would be better for portraits? Both are Autofocus therefore work with my D5100. They seem to be the same and would offer the same portrait quality (i.e. bokeh etc.) - I think the first one is older.
Nikon 50mm f/1.8 D AF Lens
Nikon AF-S 50mm f1.8G
And lastly, since they are budget lens - would either actually provide much benefit for portraits over my current zoom lens (Nikon AF-S 18-105mm f3.5-5.6 ED VR Lens)?
The "D" lens will not auto-focus on your D5100, so you would probably be better off with the AF-S "G" lens.
The main advantage the 50mm will give you over the 18-105mm is the larger aperture since the 18-105mm at 50mm is about an f/5 lens according to the lab guys. This will allow you to shoot in lower light or get a shallower depth of field (good for portraits).

And your DX 18-105mm lens will be like 27-157.5mm.

85mm has long been considered a portrait lens so 82.5mm is perfect.

Since your question is how will focal length affect your portraits, set your current lens to 50mm and see for yourself if it's OK or not. Do the same thing for a group portrait. Actually your current 18-105mm lens will be perfect for a group.

I used to own a D5100 and absolutely loved it. The 50mm 1.8G (or the 1.4G) is exactly what I would recommend for portraits on that camera. The crop factor of 1.5 from a DX sensor which multiplies the focal length of any lens, whether DX or FX, is what makes 50mm a fantastic focal length for portraits on a DX body.
If your budget is only around 200 bucks, don't sweat it. Just get the 50mm 1.8G. You'll love it for portraits on the D5100. If you have double the cash to blow, the 1.4G is an option you might look at for additional shutter speed and an even shallower depth of field to blur out the backgrounds a little bit more, BUT....it doesn't focus nearly as fast as the 1.8G. Keep that in mind. (I've owned both at the same time)
With a little extra foot work for composing your images, you could possibly use a 50mm lens as your only lens on a DX camera.
