While as a general rule, the D5100 (D40, D40X, D60, D3000, D5000, D3100) Do Not support metering with MF lenses (AI, AIS, AI modified, and pre-AI lenses), they will meter with: PC-E Nikkors, 85mm f/2.8D Micro PC, AI-P type (chipped) Nikkor MF lenses as well as any Nikon F mount lens that has as been chipped (Zeiss ZF.2 for example). Good Luck and Enjoy your Nikons!
I have very limited experience with the D5100 and none using manual focus. Given my eyes are not as good as they once were and the D5100 has a penta mirror finder I suspect it would be challenging. At least for me. Good Luck and Enjoy your Nikons!

The viewfinder is small and hard to MF through except in excellent light. Liveview has a zoom function that can help you get sharp MF, but to really MF you should tether to a laptop by using software such as ControlMyNikon. That is much, much easier.
I use my D5100 (and D3200) all the time with manual focus lenses. I don't have a problem in good light. I took this photo in the shade with the 105mm f2.5P at f5.6. I was able to focus on the clear image of the lilies stamen without relying on the rangefinder dot. I cropped off about 25% of the full frame.
In poor light the rangefinder dot is necessary. In very poor light the dot will flicker, disappear and be hard to focus. But generally that's poorer light that I take photos in.
On a tripod in any light the articulating screen in Liveview and magnified will get your focus dead on.
