Yes you can create the sites that you mentioned. You'd probably have to look for certain themes or plugins that enables you to do that.
You can do it very easily. If you wish you can take help from the plug ins available . Do Google and you will get it.
Sure. Try checking out Appthemes.com - they have several pre-built WP sites that would do this for you.
