All those are either 3" or 4.5" feature figures. Some of their 2" non-articulated ones are good too though, especially the Kanto, Johto and Galar starters.
If you're down for several figures and want to save money, there are several multi packs on Amazon that have like 8 or more figures each that will save you money rather than buying many individually.
