    The dishwasher drains into the disposal. I would be tying the clothes washer below the kitchen sink/dishwasher inlet and above the bathroom inlet.
    I have heard that I may need to separate the sink and dishwasher drains, creating a trap arm for the dishwasher

    The dishwasher needs to go up, to an air break, before it goes down to the garbage grinder. I like the deck mount air breaks, because you can see if there is a problem. It also keeps ground garbage from back feeding into the dishwasher.

    It will be ok if you do it as drawn. Assuming that vent stack is vertical.

    Ok so tying in my clothes washer (3 fu) under my sink/dish washer's trap arm making a wet vent totaling 4fu above the clothes washer is going to be fine

    I'm not a plumber. It might work but I believe wet venting is for bathroom groups only.

    Vertical wet venting is all about fixture units and UPC (908.1) doesn't mention bathroom groups.
    Bathroom groups come up in horizontal wet venting in the UPC and in the IPC under vertical wet venting, but I am not schooled in IPC and have no interest in pondering the differences. https://codes.iccsafe.org/content/IPC2018/chapter-9-vents

    That’s fine it’s more like a common vent under the code will work fine as drawn under ipc you need to use a sanitary tee instead of a wye or else it will need to be revented
