Could someone help me identify these post-1900 bottles?

Hey all,
I was bottle hunting the other day and found some more bottles, however, I've been having a lot of trouble recently with trying to really identify what type of bottles these are as well as what their possible value might be. I would really appreciate some help. Thanks. I'll list the bottles tomorrow below with pictures.

1. It says "Half Pint Liquid E.P. Davidson; Elberon, N.J." and has initials on the bottom
2. Slightly purple bottle (Ketchup I think) says Shrewsbury N.J. E.C. Hazard and Co. on the bottom
3. Petermann and Co. Union City, NJ

Never saw that milk bottle but it looks like your best find out of these three. Not sure of it's value. Post the milk bottle in the thread for dairy/ milk bottles, you may get a better response. The catsup is probably not worth much. I find lots of petermann bottles i would guess that is a common one with not much value. Thanks for the pictures.
