I have one Doubt,

Suppose If i buy License to SecureBlackBox, SecureBlackBox.PDF, SecureBlackBox.PKI then what about this DLL 'SecureBlackbox_PKCS11Proxy.dll'?
After buying license can i use that DLL which was in "C:\Program Files (x86)\EldoS\SecureBlackbox.NET\Extra\PKCS11ProxyDLL\Win32"?

SecureBlackbox_PKCS11Proxy.dll is a part of SecureBlackbox.PKI package, so you will be able to use it.

Thanks. Please clarify my another doubt.

Suppose if USBToken contains 10 certificates in it can we place Digital Signature on PDF file using those 10 certificates? or can we use only one certificate in the USBToken?

Do you want to *sign* using 10 certificates (i.e. all 10 certificates have private keys which will be used for signing) or you sign with one certificate and include the rest as a part of the certificate chain?

The second thing is possible, the first one is not AFAIK.

Sincerely yours

Yes you can. Just perform the same set of operations that the sample demostrates but with 10 different certificates.
