yes, you need to make site viewable to anyone and then set the pages you don't want them to see as only available to registered members and the ones you do guests and registered members.
You do this via admin>pages and menu
If the page you wish them to see is accessed from a link and not a tab in the menu then you click and drag the page to the hidden section and set permissions for this page appropriatly

i want do that with not viewable site for guests

i wish do this manually for some special pages

You will have to do it all manually for each page/section. You can also set what guests can see via permissions/roles
There is no way you can have a few select pages viewable if you set your site no not viewable to guests via global privacy.
I suggest you reread what I have told you and you will see I have told you exactly how to do what you want to do.
