Buy a router. You may need some help picking the right model and
configuring it though (depending on what's in there already), but
that should solve most of your issues.

If I buy one more LinkSys/NetGear Broadband Router (1 WAN + 4 LAN) and
connect to the LAN cable which we got connection from Building, will it
be OK, since we got assigned 192.168.0.10 as IP address from Building
Router, if I put one more Router for my office, can I use default IP
address? Or do I have to change to the 192.168.102.x something like
that?. also the building has already one Router and can I connect one
more Router to the LAN port of the other Router which was serving for
all three offices?. Please let me know. Thanks.

1) The WAN port won't be used and you'll lose a LAN port to the main router
so a 4-port router will only yield 3 ports - you could go for an 8 port
router or add a switch somewhere after.
2) You would probably want to pick a different LAN address from the main LAN
to make things simpler. You could set up something like this:
192.168.0.1 192.168.0.2 192.168.20.0-255
WB cable --> main router --> Office 1 Router --> ----------------------------
| | | | | | |
| PC1 PC2 PC3 PC4 PC5 PC6
|
| 192.168.0.3 192.168.30.0-255
|--------> Office 2 Router --> ----------------------------
| | | | | | |
| PC1 PC2 PC3 PC4 PC5 PC6
|
| 192.168.0.4 192.168.40.0-255
|--------> Office 2 Router --> ----------------------------
| | | | | | |
| PC1 PC2 PC3 PC4 PC5 PC6
\
\ 192.168.0.5 192.168.50.0-255
\------> Office 2 Router --> ----------------------------
| | | | | |
PC1 PC2 PC3 PC4 PC5 PC6
I'm not sure what the approved subnet addresses are - I used 192.168.20.x (30,
40 and 50) - I'm not sure what the approved answer would be. You could also
have the main router break the 192.168.0.x address space up and spread the
250+ numbers to the various offices in blocks.

If I use 172.16.1.x Netmask 255.255.255.0 for my own LAN within my
office, will it be OK, is this IP address range is approved for Local
LAN?. I don't want to use 192.168.xx.xx, also if I have one more office
in different location, can I use the continuation of IP address range
172.16.1.xx for that office location, since I want to all the machines
in both offices should communicate each other, if I want that way, do I
should have a separate leased line between these two offices?. Can I do
that way?. thanks.
