Small LAN, 5 PCs. How to protect one PC inside LAN(isolate from other PCs):
to prevent from connecting other computers to that PC, or share files?

Several ways:

1) Software firewall on that PC. Block all incoming access and
disable "File/Printer" sharing.

2) Add a separate router. Makes this PC part of a second "LAN"
network and remaining PC would not be able to access it.

Adding exception is not possible if the user is a regular user (non admin)
How make sure "File/Printer" sharing disabled?

Uncheck "File and Printer Sharing" check box in Windows firewall Exception
or enable "Don't allow exceptions".

The special server (hardware) has been attached between provider's DSL cable
and dsl modem, for interception and recording all voice conversations (and
internet traffic also, seems). One PC have access to that server(probably
some management software installed) for monitoring conversations
periodically. Is there way protect or scramble internet traffic between one
of the rest PCs and WAN? Or not possible, and each packet can be read by
that server?

Is that a VOIP box that allows you to make regular phone calls to any phone?

How do you know the "server" monitors conversations?

What is this "server" you're talking about? Btw, your original post asks a
completely diferent question. Start a new thread if you have a new question.

Go to the switch device (which might be the frontend to a router) and
configure that host (by MAC or IP address) as isolated or inaccessible to
the other hosts. How to do this depends on what switch/router you use. I
used to be able to do this in my old DLink router but not in my Linksys.

On the host that you want to isolate, you could disable the exception in
Windows Firewall that allows the file and printer sharing protocols/ports.
Or you could go into the TCP properties of your LAN connectoid in the
Network applet in Control Panel to disable the File and Printer Sharing
protocol.
