Wire connectors don't count extra. Each wire that enters the box and makes a joint is counted as one wire. So, if you hae a joint with three wires that counts as 3. Each wire that enters the box and is terminated on a device counts as one. Each wire that passes through the box without making a joint counts as only one. The code limits are based on the cubic inch size of the box (should be stamped on the box) the size of the cable, and the type of the box (and a few other things). However, five 14/2 cables coming into a plastic double-gang switch box is probably not excessive.
