You would need a 4-wire 4 channel multiplexer. Typically multiplexer are part of a complex test rack and most come in high density and not at this low channel count and rarely a USB version.

What is your budget? if you go for a cheap multiplexer, the trace and contact resistance of the multiplexer degrades your measurement accuracy.
