What is the weight of a standard 2x4?
It varies. Is it yellow pine,spruce,and wet or dry ? A 2X4 Spruce/ Pine/ Fir KD 1.375 lbs per foot ( Used for interior building in projects New England ) 2x4 Pressure Treated southern yellow Pine 2.175 lbs per foot. (Used for exterior building projects ie. Deck railings) That actual weight will vary depending on exactly which species, and how dry / wet the wood is. But these are generally excepted weights we use in calculating shipping weight for these types of wood.

What is the r value for pink fiberglass insulators?
It varies with the thickness of the insulation Generally, about R-3 per inch. 3 1/2" for a 2x4 stud cavity is R-11. 5 1/2" for a 2x6 stud cavity is R-19. But if there is any airflow it greatly reduces the insulating value. Also, the thermal bridging of wood structures reduces the performance of fiberglass insulation.

Is pine bullet proof?
It depends - logically - on the caliber of the bullet, and the thickness of the pine. A deer rifle bullet will penetrate a 2x4 with no difficulty, and may or may not penetrate a 4x4. A .22 will penetrate neither, a .50 machine gun bullet will penetrate an 8x8. Loosely speaking, I would not consider pine to be a bulletproof material.
