Sometimes we may want to update multiple nodes at once. Views Bulk Operations may help if you want to set the same value for a field of multiple nodes. But if you want to set different values among a set of nodes, then Views Bulk Operations could not help.
1. Download and enable the module. (I used the 7.x-1.x-dev version)
2. Create a view with table format. (This is not necessary but better user interface)
3. Add the desired fields. For those which should be editable, set the display formatter to editable as depicted below.
