Vintage Desert Ironwood Natural Wood Chess?Hand Turned Abstract Art Decor Gift

Set of 4 beautiful hand tuned wood decor pieces: I’m not really sure what these are supposed to be/represent. They resemble chess figures. One is labeled desert ironwood, but I’m not familiar enough with wood species to be confident in specifying. Size Ranging from 3.5-5” tall. Please see all photos and if you have any questions please ask, thank you.
