First, for all abilities there should be a post duration and a cooldown to avoid spamming, something you should add. For reference look at pretty much every other CS in this RP.
Now onto the actual abilities:

#1: So if I get this right she has an increase of speed, being able to attack multiple times with kicks and slices? If so, fine.

#2: It's pretty straight forward, so I guess it's fine.

#3: So she hits a target then shoots Spirit Energy at them.....Fine with me.

#4: Can't really picture it, but, it doesn't sound too bad. So it's fine.

All I can say is add post duration's and cool-downs then you're good to go.
