Just with regard to the content of the photos (rather than exposure issues) I'd prefer to see a bit more in the way of 'head on' shots with faces, and with the puck on display. I also think a much closer crop on the action would give your images more impact (but probably make your focus come a bit more under scrutiny).
Exposure-wise I think you'd have been better off using manual exposure and using trial and error to get the results you wanted, if you were unable to take a light-meter reading over the ice. Shooting a team in black against a team in white will never help your metering (in relation to shutter speeds), especially with all that white ice, and white boards around the edge.
If you're able to (in advance of the game/practice starting), hold a grey card out over the playing surface and either use the result to set a custom white balance, or use it to measure your post-processing white balance levels. If you know one of the players, ask him/her to take it out to the centre of the rink while you shoot it.
With AF for sports photography I always use a single AF point, especially when you have fast-moving, erratic-direction subjects. Using more than one can cause the camera to leave the person alone that you want to catch!
With apologies if there's some way of seeing this myself, what were your final exposure results (SS, aperture and ISO) and what programme were you shooting in? In an indoor environment with poor lighting (and just guessing from a look at your images) I'd have expected at least 3200 to be required to get 1/400th shutter speed (too slow to properly freeze action) at f2.8. You then have to decide whether you want noise-free or blur-free images if you have further ISO options. I always decide to go for blur-free and jack my ISO all the way up. Better to have caught the image with noise, than to have your image ruined by movement blur. I can see one of your images was shot at ISO6400 but I'm not sure about the others.
Maybe treat this as your learning curve and shoot a proper game when the lights are fully-on! Pro-hockey games tend to have strobe set-up, about which I know nothing (basketball arenas too), for some photographers so they'll always have a head-start on what you can achieve without such assistance, so don't be downhearted!
