Speaker ohm pairing question

[east Boston guy]

Hello all, yesterday I picked up an 8 ohm, passive PA monitor. I have a Marshall DSL 40 with a 16 ohm speaker with five speaker outputs in back, and I have a fender, twin reverb with 2, 8 ohm speakers in parallel.hooked up to a two notes torpedo reload attenuator. The five outputs on the back of the DSL 40. Are as follows 1,16 ohm. 1,8 ohm or 2,16 ohms 1,4 ohm or 2,8 ohms. I assume these are all in parallel. Could anyone give me any advice on the best way to hook this up and could I use the torpedo reload attenuator to connect to. I’ve posted pictures of both dsl40 and torpedo reload back panels. Thanks in advance for any help I might receive and I hope everyone has a nice Thanksgiving.
