You can connect one phone _line_ with multiple phones sharing the
line. When you have two or more phones in one house, all using the
same line, they are essentially connected in parallel. The only issue
is how many ringers can you ring at once, as they all use some of the
limited ring current capacity. Most new phones use very little
current, so this should not be an issue. Old phones with mechanical
bells would stop ringing if you tried to put more than 5 on one telco
line.

Think of the phone line as a pair of wires, say green and red. The
green/red wire pair will connect from one jack to the next, to the
next, etc in a line or you can tie them all together in one place,
called a home run. Just remember to wire green to green and red to
red. Usually green and red connect to the two center pins (3 and 2
respectively) in an RJ-11 jack.
