No, Homo habilis does not have a sagittal crest. Sagittal crests are present in some species of early hominins like Paranthropus but not in Homo habilis.
Homo habilis is known for using simple stone tools, such as choppers and scrapers, which were used for cutting and processing food, hunting, and other tasks. These early tools indicate a level of cognitive development and adaptability of early humans.
Paranthropus boisei had a larger, more robust skull with a prominent sagittal crest for muscle attachment, while Homo sapiens have a smaller, more gracile skull without a pronounced crest. Homo sapiens have a more pronounced forehead and smaller cheekbones compared to Paranthropus boisei, who had a flatter forehead and larger cheekbones. The teeth of Paranthropus boisei are larger and more adapted for chewing tough, fibrous vegetation, while Homo sapiens have smaller teeth adapted for a wider range of diets.
The plural form of Homo habilis is Homo habilis, the plural form of Homo erectus is Homo erectus, and the plural form of Homo sapiens is Homo sapiens.
There is some dispute about the "seven" names. However, we do have "homo sapiens", "homo neandertalensis", "homo heidlebergensis","archaic homo sapiens", "homo ergaster","homo erectus", and "homo habilis".

Its brain size has been shown to range from 550 cm3 to 687 cm3.
Saggital, longtitudinal, horizontal there is also mid saggital
Saggital, coronal, and transverse.
saggital
Sagittal means arrow, and the word refers to a body plane, section of cut where the cut is vertical from front to back. A midsaggital cut will separate the object into two equal and opposite halves. The amputation of an arm is a saggital cut.

Only one, that is the saggital plane.
No, the sagital suture links the two parietal bones.
