Words for different levels of crying

Every human has his own ways of expressing pain. Levels of crying vary with sex and age. A man's cry is different from a woman's. Similarly, a toddler's cry differs from an adolescent's. More importantly, however, there are no current studies or research about the different levels of crying. Nevertheless, a blogger made an illustration titled Types of Crying where two factors are considered: Pathetic-ness and Sympathy Elicited.

Whimpering: Soft crying usually including few or no tears at all; Often incorporates muttering and/or high-pitched sighs.

Silent Tears: Soft, inaudible crying that does not draw attention; May manifest only in a single tear rolling down one’s cheek.

Sniveling: Audible, but soft crying, also prone to muttering and erratic breathing; May also show signs of drool or mucus.

Weeping: A gentler version of sobbing; Involves soft, steady stream of tears with some times lightly audible signs of distress.

Sobbing: Heavy crying with a large volume tears flowing steadily; Generally audible but not inappropriately loud.

Hyperventilate-Crying: Forceful crying causing heavy breathing, resulting in the inability to speak or produce sounds even resembling words.

Blubbering: Unattractive, loud crying. Characterized by mutters, truncated, erratic breathing, clinched facial expressions and hunched posture.

Scream-Crying: Violent crying accompanied with bouts of yelling or sometimes shrieking. May also include slapping, punching or other physical expressions of distress.

There is a certain theory about 5 stages of grief formulated by Kubler-Ross-- the Bereavement Theory as well. It may not answer your question but it entails that every human being has the same bereavement process.
