You might be new, but SunOS 2.5.1 is more archaeology that CS nowadays.

1. Why is "Makefile" being used as a command? What does it signify? It is not defined anywhere in any other make file also.
There is no evidence in the posted material Makefile is used as a command. Nowhere is it executed. That would be quite surprising anyway.

2. What is a .mac file in Solaris? what is it's purpose?
No specific purpose, there are no .mac type with Solaris, the developers might have chosen that extension for macros or whatever.

Same as the above. The best guess would be some defines.

ypmake(8) System Manager's Manual ypmake(8)
NAME
ypmake - rebuild Network Information Service (NIS) database using the make command
SYNOPSIS
cd /var/yp make [options] [map]
OPTIONS
The options argument can be used to override the default values of three special variables used by make: Instructs make to use the source
files in the specified directory. The default is /var/yp/src. Instructs make to construct a domain other than the master's default domain.
The DOM variable in the /var/yp/Makefile file must be set to the domain name before running make. If you run ypsetup, the DOM variable is
set when you specify a domain name. Specifies the database routines used to store NIS maps. The choices are: btree -- Recommended when
creating and maintaining very large maps. dbm/ndbm -- For backward compatibility. This is the default. hash -- A potentially quicker
method for managing small maps. When non-null inhibits updating of the new database files using the yppush(8) function. The default is the
null string.
To override the default values of these special variables, an options argument format of special_variable = value is used. See the EXAM-
PLES section for an example.
The map argument supplied on the command line instructs make to update only the specified map. The specified maps are those located at
/var/yp/{domain}, where {domain} is the NIS domain name. Some typical entries for the map argument are passwd, hosts, and networks. Typing
make passwd creates and updates the NIS password database, if it is out of date. The make command distributes the updated password database
to the slave servers using yppush(8). Therefore, typing make host or make networks creates and updates the host and network files,
/var/yp/src/hosts and /var/yp/src/networks, respectively, on the master and slave servers.
See ypfiles(4) and ypserv(8) for an overview of NIS.
DESCRIPTION
The make command uses the /var/yp/Makefile file to build an NIS database. With no arguments, make creates databases for any NIS maps that
are out-of-date, and then executes yppush(8) to notify slave servers that there has been a change.
Note
Execute the make command only at an NIS master server machine. If it is executed from either a slave server or an NIS client machine, the
created changes will only be overwritten when the next NIS master server machine update, using ypxfr(8), is performed.
RESTRICTIONS
You must use the same database format for each map in a domain. In addition, a server serving multiple NIS domains must use the same data-
base format for all domains.
Although a Tru64 UNIX NIS server that takes advantage of btree files will be able to store very large maps, NIS slave servers that lack
this feature might have a much smaller limit on the number of map entries they can handle. It may not be possible to distribute very large
maps from a Tru64 UNIX NIS master server to a slave server that lacks support for very large maps. NIS clients are not affected by these
enhancements.
EXAMPLES
This example causes make to create a password NIS map for the domain NewDomain instead of for the default domain: make DOM=NewDomain passwd
