Bleach pic OP here. At least in the US, the contraction for a pound (measurement of weight) is "lb". Make it backwards, and you get "bl". It probably would make more sense if I wrote "dnuop" instead of "pound" flipped, but it would've been even less guessable then.
The first pic was definitely the hardest, but once you figured out "e" and "chi" minus the eye, it should have been pretty easy to fill in the first bit.
