If someone has allergies does that mean their immune system is weak, or if they do not suffer from allergies, their immune system is awesome?

Not at all.

An allergy is a complex immune response to a specific stimulus in which the body over-reacts.  

Trying to quantify the strength of an immune system is also difficult.  It has a number of factors that comprise it, and can excelt at one type of protection, and suck at another due to diet, genetics, location, stress and other factors.
