Light weight dumbells are best for seniors to use.
Dumbells can help to tone your pecs if you do the correct excercises.
I believe your question is, how to estimate how much one can safely lift. Correct? You should always play it safe, when dealing with heavyweights. If you don't have anyone to spot you, I'd advise using dumbells aposed to a barbell. If comes the occasion you've to complete failure and cannot lift the weights any higher. You can just drop dumbells, a bar bell could drop on your chest, neck or head. Causing serious injury or death. Try not to show off too much in the gym. Your results will show off for you.
I think about 8-14. Does not stunt growth.

Nope, you need protein for muscle gain but you DO need some fat from your meals to supply yourself with energy; both for staying alive, and to lift those heavy dumbells :)
