How should I go about making nine custom sword swings that are appended to the number pad keys?

I have had an idea of a very competitive sword-play type game, but for it to be as hard and as realistic as possible with a keyboard, I want to make it so that you have the ability to swing your sword in any direction that you please. This would also all be in first person.

My plan is to attach certain keybindings to the keypad on the right of your keyboard that represent which way you are going to swing your sword. Here is my example:

7 = uppercut, to the left

9 = uppercut, to the right

8 = uppercut

4 = slash, to the left

6 = slash, to the right

5 = (changeable, but maybe something like blocking w/ shield or whatever)

1 = downcut, to the left

3 = downcut, to the right

2 = downcut

If these were to be made, and collision correctly programmed, it could make for a very nice experience.

So I am wondering, how should I go about making the animations for the keys in which direction that you would swing, meaning, if I press "9", how do I make the sword swing in an upward and right diagonal slash? I have been an environment modeler for a while now and have never delved into these areas so I am quite clueless. I have all the tools that I believe I will need and just need to figure out how I should use them in this matter.

If you could list me some things to look up, research, maybe a link to some videos, or just flat out telling me. All are appreciated, and even if you don't reply, thank you for looking and taking the time to read my ideas.
