You need a receiver and transmitter at each end, but these come in a single chip so that's one chip at each end. Same as RS-232 in that regard but 2x the number of wires required.
would this require 4 MAXRS485 convertors?
Yes, but you wouldn't use that chip, there are plenty around that are for full duplex, eg LT1791, ISL31483 or my favourite the LTC490, duplex in an 8-pin pack.
