You can programatically do it with dynamic SQL or you can copy paste a bunch of lines only changing the table name (Object name)..

Simplified syntax for GRANT

GRANT { ALL [ PRIVILEGES ] }

| permission [ (column [ ,...n ] ) ] [ ,...n ]

[ ON [ class:: ] securable ] TO principal [ ,...n ]

[ WITH GRANT OPTION ] [ AS principal ]

Simplified syntax for DENY

DENY { ALL [ PRIVILEGES ] }

| permission [ (column [ ,...n ] ) ] [ ,...n ]

[ ON [ class:: ] securable ] TO principal [ ,...n ]

[ CASCADE] [ AS principal ]

Just change the object name and repeat the code
