Why when squeezing fresh lemon juice on my steamed frozen asparagus - does the juice from the lemon turn the asparagus juice a pinkish red color?
It's possible that the asparagus juice contains an indicator chemical which is reacting to the acid in the lemon juice. (Note that I don't know exactly which indicator is involved, or even if this actually happens; I'm just offering an explanation for the phenomenon you say you've observed.)

Which juice cleans pennies the best lemon grape or orange?
Lemon juice. It has a pH of 2.3, whereas orange juice has a pH of 3.3. What is being cleaned off is the CuO and CuCO3 that forms on the penny. Both O2- and CO32- are bases, so the stronger the acid, the more effectively they will be reacted away. I did a quick online search for the pH of grape juice but did not find anything, but given that it lacks the sour taste that orange and lemon juice have (an indicator of acidity), I would have to assume that it is not as acidic as either lemon or orange juice.
