Your Maximizer Business Partner (or Maximizer Support) can help you with the specifics, but the general answers are:
>1. How many custom views are available?
As many as you care to create, at least in theory. (Practical considerations like performance, screen real-estate, etc. may limit the actual number of views in use at any one time.)
>2. How can I view data from custom views in maximizer?
Normally you create what is called a "Business Partner View" (sometimes called a "BP Window") which adds a window/tab to the standard Maximizer interface. See the Customization Suite documentation and samples for details.
>3. Can I do search on custom views?
You can incorporate search logic into your custom code, yes.
