You could get 2 in there if you aligned them perfectly and pulled them
in together but it is still an over filled conduit.
He also has another issue, the existing box is probably not big enough
to terminate 2 cables.
Probably not applicable in this case, but you are allowed to ignore
conduit fill calculations for cases where the cables are passing through
a short length of conduit sleeve. What was it, 24" length max?
It is 24" max, but you are *not* permitted to simply "ignore conduit fill calculations". Rather,
"where conduit or tubing nipples having a maximum length not to exceed 600 mm (24") are
installed between boxes, cabinets, or similar enclosures, the nipples shall be permitted to be
filled to 60 percent of their cross-sectional area ..." [2005 NEC, Chapter 9 Tables, Note 4]
NO, NO, NO. Do not add two j-boxes. add one 4" sq box at top of EMT.
You will need to pull the wire back out of the outlet box anyway to
add on the box. Now cut and strip the old wire so you have 6" inside
the box, this wire is now too short to make it back down the the
oulet. Use 2 new runs of 14-2NM to go to the old box and to the new
box for your light.

If you're worried about protecting the wire and it's in a fairly dry
location, have you considered MC cable? It's a lot easier to install
than conduit and the wire is inside the metal cladding. You don't have
to buy a whole roll and you can probably get the length you need cut at
many hardware stores or even one of the Lowe's/Depot stores. You don't
have to buy a Roto-Split tool for a few connections but there are easy
to use one screw connectors having an integral insulated bushings used
to install the cable into the conduit boxes. ^_^

There should be a connector at the top of the EMT to prevent pullout and to
act as a bushing. In this case you need a 1/2" EMT to Romex changeover co
