I would say yes to the first question.
A cord and plug disconnect is allowed for motors single phase < 1 HP.
Whether 400.7(A) would allow this to be run in cord is something else.
The use of a cord & plug to connect the air handlers has been discussed here a few times. One of those is here:

My memory from the various posts is that most folks consider it a violation of 404.8 unless the unit is listed to be cord and plug connected.
As far as the two motors on one circuit, you may find a problem in the unit requirements per the nameplate. Either or both may be listed with a MAX OCP of 15 amps, so check your nameplate,
