[SalesForce] How to give an access on an object to All the profiles which are in system

Standard Profiles come default with set User Permissions. User Profiles and their customizations are set based on the org type:

In Contact Manager, Group, and Professional Edition organizations, you can assign standard profiles to your users, but you can't view or edit the standard profiles or create custom profiles. In Enterprise, Unlimited, and Developer Edition organizations, you can use standard profiles, or create, edit, and delete custom profiles. For standard profiles, only certain settings can be changed.

Each standard or custom profile belongs to exactly one user license type.

Essentially, these profiles are set up and only some of them allow certain functionality. Not all of the profiles allow access to certain objects (specifically, profiles associated to Portals are very restrictive). This is just how the profiles are set up.

OWD is the most restrictive permission in terms of data sharing, it controls what the least amount of access is to the object. Since you've opened this up to Public / Read Write, the spotlight shifts to the Profile.

The Profile Controls whether you can Read, Create, Edit, Delete an Object's records, if you've granted View All and Modify All on the Object, users assigned to that Profile should be able to do pretty much anything with records of those objects.

The last piece in the puzzle could be Record Types, for a User to be able to create records of a certain RecordType, it must be available to their Profiles.

Here's something I wrote earlier explaining this, which might help.
