Q.Can you pot a young lipstick and a young polka dot together?
I have a young lipstick and young polka dot plant and am wondering if they are compatible together in the same soil? What soil would be best for these guys?

Unless they are stated to be direct companions then I would not do this. The reason companion plants work is that they are symbiotic. One or both provide something to each other. In this case, they will compete for the same nutrients, making this an unsuitable pair.
Both of these plants will be just fine in standard potting soil, as they are both pretty tolerant of a range of soils.
