I'm sorry, I thought you were asking for plants that would be compatible with the Pachypodium and Euphorbia you have potted together. Let me try to be more helpful in general.
Of the 4 Haworthias you listed, the first two will grow much faster than the last two. They are all clumping plants (so plan for offsets down the road) but some reproduce more quickly than others. I am a big fan of the Haworthias though their flowers tend to be pretty bland. They tolerate drought very well and do not require a lot of pot space. When in doubt, put them in a more protected location. So not full sun, more like part sun or filtered light, definitely strong light but not full blasting overhead sun.
The two Pachyverias you have listed are hybrids between a Pachyphytum and an Echeveria. They tend to be powder dusted and the flowers are interesting, sort of fleshy because of the inflated sepals. I am not familiar with the cultivars listed. These plants require the same care as Echeverias and they tend to resent really high temperatures.
The Adenia is an interesting plant because of its flask-shaped or globose caudex (to ~2 feet). Info from the Pachyforms book (which I highly recommend): apparently best grown in warm greenhouses, must be kept above 50°F (ideally above 60°F) during winter, with daytime highs in the low 70s if possible.
