LAN stands for "Local Area Network" while it can cover a large area they usually don't. For example an office building generally uses a LAN. And if in a skyscraper that LAN can be quite large. On the same token, if you have a router at your house, and all the computers on that router are connected via ethernet cables. That is also a LAN, but is much smaller.

A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
There is only one type of LAN. If you are asking for the type of networks then they are the following: LAN - Local Area Network WLAN - Wireless Local Area Network VLAN - Virtual LAN WAN - Wide Area Network MAN - Metropolitan Area Network SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network PAN - Personal Area Network DAN - Desk Area Network
LAN is a Local Area Network which covers a small physical area, it is mostly used in school, colleges, office, home, and in airport.
