You can disable it if you don't use them/have any.
LocalServicePeerNet Provides identity services for the Peer Name Resolution Protocol (PNRP) and Peer-to-Peer Grouping services. If disabled, the Peer Name Resolution Protocol (PNRP) and Peer-to-Peer Grouping services may not function, and some applications, such as HomeGroup and Remote Assistance, may not function correctly.
netsvcs Multimedia Class Scheduler Service. Enables relative prioritization of work based on system-wide task priorities. This is intended mainly for multimedia applications. If this service is stopped, individual tasks resort to their default priority.
NetworkService - The Network Access Protection (NAP) agent service collects and manages health information for client computers on a network. Information collected by NAP agent is used to make sure that the client computer has the required software and settings. If a client computer is not compliant with health policy, it can be provided with restricted network access until its configuration is updated. Depending on the configuration of health policy, client computers might be automatically updated so that users quickly regain full network access without having to manually update their computer.
I do not think you should disable this.
LocalServiceNetworkRestricted Provides support for the NetBIOS over TCP/IP (NetBT) service and NetBIOS name resolution for clients on the network, therefore enabling users to share files, print, and log on to the network. If this service is stopped, these functions might be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.
Do not disable it.

Other things to look at to save bandwidth would be disabling google update, flash player update, maybe even windows update and instead run them manually
