Hello!
For the 1st one you should look at one of the products at the store area more closely (looks like you've already found another number the same way).
For the 5th one you need to sit on one of the bar stools at the store area to be able to see it.
The key to unlock the last number is finding cheese (try climbing some cave walls). Hope you'll figure out what to do with it after you get it!
Sorry about the writing on the recipe list! The third item is "1 beet". The first "e" is really barely visible. -__-"
