Hi I am working on my player model and want to use bones in my figure is their any good tutorial on making great bones so I can make an realistic animation??

It depends on what program you're using - are you using MED? Just my personal opinion, but MED is absolutely terrible for designing/animating models in...I might look into something better suited for animating. I use Milkshape which is pretty good and fairly cheap, and I hear Blender is excellent, though I don't use it myself. I know there are some great animation tutorials for Milkshape, and I bet there are for blender too.

I use MilkShape for rigging and CFX for animations
You can take, let's say 30 minutes to learn how to use these tools

This is not the main issue to create a good animations
A part from personal artistic skill , you should collect images of real walking, running , jumping etc animations sequences to use as examples

You can find them on the WEB or simply use the animations supplied by 3DGS

I been using med for the animation and then turned to another software that is complicated. I might go the milkshape route.
But I want to know that if I make the bones and animate them is their anyway that I can attach that bone to multiple 3d models So I don't have to keep remaking them for different models?
