1. They don't give you anything, they grant
2. Clause A is a total mess. They can't grant you the right to copyright or use .... because they don't have those rights. They are already your rights from the second you press the shutter. Also a model release is not for the use of images, sound, video.... again as copyright holder all these are yours to do with as you please. A model release is a grant of rights by the model to use their likeness.
3. Clause B - they don't own those rights so can't grant them.
and on and on....
You really need to get a lawyer to do a proper one, or else get one from a reputable Professional Photographer Org.
Conclusion
This is a (really badly drafted) contract, not a model release. You have written it to protect you against stupid, when stupid will go ahead and sue anyway. A contract should define the terms, schedule and deliverable of a deal, not list all the stupid you don't want people to do.
The one thing your Model Release doesn't do? Release. There is no grant of rights to use the models likeness, which is the whole point of a release.
