I do not know Xming, but i suppose it is some sort of X-Server software, like the well-known Opentext Exceed (formerly known as Hummingbird Exceed). In this case: yes, you can.

X-Windows is a client-/server-system, where you have locally an "X-server" running, which manages your graphical display. Think of it like a driver for your graphic card along with a - networked - function library so clients can make use of its services. This part is installed locally, at your client (yes, the "server" running on the "client" can be a bit confusing, but with the explanation above it should make perfect sense).

A "X-client" is a software which makes use of these functions a X-server offers. Examples of a X-client would be "xterm" or "Firefox". These X-clients will run on any networked host (your client as well as any server) and will connect (via the "X-protocol", a specialized network protocol) to your local X-server to display (in a window) their frontend on your display. They do so by using the services your X-server offers.

Which X-server an X-client uses is determined by the environment variable "DISPLAY", which should point to a display managed by a X-server. Notice, that X-servers have a sort-of authentication, managed by the "xauth" and the "xhost"-utilities. For a quick test you can use xhost + to allow all hosts to use the X-server. Once you found the setup to be working fine-tune this to allow only the hosts you want.

No, in fact you do not. You just have to install the X-clients.

I hope this helps.

Name
       ris - remote installation services utility

Syntax
       /etc/ris

Description
       The  utility performs remote installation services which install system software to a client machine through the TCP/IP local network.  The
       client machine can be a VAX or a RISC machine.

       The server on which the remote installation services area is located can be either a VAX or a RISC machine.

       The remote installation services utility uses the directory as a base.  When you install the first product to the utility creates a  remote
       installation services area.  The area is called either or

       The  area contains one or more ULTRIX software products.  Each product contains the subsets of the kits that can be installed to clients on
       a network.  Clients registered for an area install software over the network to their processor.

       The utility performs the following functions:

       a -  Add client

       r -  Remove client

       s -  Show products in remote installation environments

       m -  Modify client

       i -  Install software

       You must use the utility interactively to set up a remote installation services area.  After you have set up a remote installation services
       area on the server, you can use the utility either interactively or from the command line to manage clients.

       The directory also holds a subdirectory, This directory contains a database file, that you can use to manage multiple clients.

Examples
       The example that follows invokes the utility interactively:
       # /etc/ris

       A menu appears from which you can select options to perform functions.

       The examples that follow manage the client using the command line.

       The syntax of the command to add a client follows:
       /etc/ris -a <clientname> -h <Ethernet_address> -p path,product[,product]

       The following command adds client and allows that client to install a product over the network:
       # /etc/ris -a bergal -h 08-00-2B-03-05-8B -p ris0.mips,product_1

       The syntax of the command to modify a client follows:
       /etc/ris -a <clientname> [-h <Ethernet_address>] [-p <path,product,product>]

       The following command modifies client and allows that client to install a product over the network:
       # /etc/ris -m bergal -p ris0.mips,product_2

       The syntax of the command to remove a client follows:
       /etc/ris -r <clientname>

       The following command removes client
       # /etc/ris -r bergal
