One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
A large number of reactions occur in the cell, many of which requiring enzymes to work. From the creation of the ATP used to energize the cell to the creation of proteins from RNA, each new type of reaction needs its own enzyme to work, and often need dozens if not hundreds of that enzyme to do the reaction at the pace it needs.
The arrangement of it's active site. Some enzymes just provide a place where two reactants can be in a protected environment for the reaction, some enzymes stress bonds of reactant to lower the reaction activation energy and some enzymes have catalytic properties due to the arrangement of the various amino acid R groups in their active site. One enzyme, one substrate(s) and one function. So, many different classes of enzymes. Very much so
many enzymes require vitamins and/or minerals to function properly. Without them, they cannot catalyze their reaction.
no, every enzyme has a different shape giving it a different job or function

Yes, cells contain many enzymes which are able to function inside the cell.
No, because an enzyme is a protein. The function of each protein is determined by its shape. The protein is only that protein and can do its job only when it is in its specified shape. Since an enzyme is a protein, it has a specific shape that is made for one particular substrate.
Depends on the enzyme. Acid activity around the enzyme is the number of protons around the enzyme, which then warps and changes the electrostatic field in localized positions of the enzyme. Think of the enzyme as weirdly shaped glove with a crazy number of fingers, trying to grab specific reactant molecules and hold them in arrangements where they react with each other. The changes in electric fields cause by the acid/base balance moves the glove's "fingers" to either work better or worse in grabbing and aligning the molecules to be reacted. While most natural enzymes work in acid systems, such as digestive enzymes, there are many enzymes that need alkaline conditions to function best.
Enzyme supplements are creating a real buzz these days. As with many supplements a doctor is required in finding the perfect balance of fat burning enzymes as well as muscle toning enzymes as building to many enzymes in body may cause abdominal and internal issues.
Enzymes can have varying concentrations inside a cell. If the need for an enzyme is small then few enzymes will be in the cell however if there a signal to the cell that would cause a drastic need for more enzymes then the production and thus the concentration would increase.
