1- How add a customs elements in map (textures, sound etc), and send this at hammer ? How compress in VPK ?
Place your custom stuff in the correct folders.
What I like to do is for example all my custom textures go into a separate folder inside the materials folder so like materials/Lp
Sounds go to sounds/Lp etc.

Hammer should find them automatically if you restart, materials should show up after a reload of the texture browser.

Once they're in the map and your map is done use pakrat to include those textures into the bsp. This will always work and it's the only way to get custom stuff into the workshop.

2- How do a custom elements of gameplay ? Like the elements of Reepblue : The custom paint, the specials cube etc ?
Scripts and I/O this is rather complex stuff though, make sure you understand the basics first. Once you finished your work it's the same story again; pakrat and profit.

3- How add a special cube with a special texture without remplace the original cube ?
There's a thread about that which has been linked before

4- How modify/include a models in game ?
Well, modifying models is quite hard, it would require you to de-compile a model, adjust it and re-compile it again. In general you need a 3D-modeling program like maya, 3dsmax or something similar to create the model, then use a plugin to get it to the proper file format for hammer. Then again pakrat it before releasing.

5 - How do a effect of destruction ? Exemple : A brushs that falling.
physboxes are mostly the way to go for falling objects, but the destructed theme also requires good texturing and use of destroyed models. A good destroyed map doesn't need falling stuff, although it does look sweet.
