I believe all but three are grammatically OK.

In <<1-1. He narrowly escaped from being drowned. >> , the word "from" is not needed. If you leave it in, people will know what you mean, but it shows lack of fluency with the language.

In <<2-3. He dropped himself on the floor and crept toward the door.>>, the word "himself" is not needed. " to drop oneself" may seem to make sense as a reflexive verb, but it just isn't done that way. The best way to say it is:
"He dropped to the floor and crept toward the door."

(In <<2-2. He dropped on the floor and rolled himself to extinguish fire on his clothes. >>

"Rolling oneself" is not grammatical, because it descriobes a situation of one person actively rolling another object or person by pushing it around. Also, "dropped to" is better than "dropped on". A better sentence would be "He dropped to the floor and rolled around to extinguish the flames."

DrWLS is correct.
