Need help creating these effects

And yes Inscape Digital, I know how to mask and overlay UI shots now. 

This is for Hitfilm 4 Express

1. The portal effect used by Blink in Days Of Future Past where it shows the scene in the portal from one camera angle, when in fact that scene could be happening right next to her.

2. How to walk through a portal. (If there's a green screen method, it's ok, but I'd ideally prefer no keying)

3. A sonic scream effect (where the waves warble out, like Black Canary).

4. The Cyclops/Superman eye laser where it's a continous laser being fired (I don't have the lightsaber pack so I cannot do it with that pack)

5. The Beast effect where the skin colour changes.
