How should i think about tpi? is 24 or 32 better for cutting stainless bolts?

This article is informative; http://diyhousehelp.com/tools/choosing-the-correct-hacksaw-blade-tooth-count

How long will one of these blades last on average if you use it an average of once or twice a week for small projects?

Depends on the material. Copper and aluminum are soft metals. The blade is going to last a long time. Stainless steel and harden metals not as long. I use mine on all sorts of different materials and I get at least a year out of each blade.

Starrett green stripe vs Starrett red stripe blades? What is the difference?

I had no clue, so I googled it & this is what I found. Greenstripe® These hardened-milled tooth blades are shatter resistant and are the best blade for interrupted cuts or when the blade is subject to excessive stresses. Redstripe® Constructed of uniformly hardened high speed steel, these blades maintain their cutting edge on the most difficult to cut materials, held securely. Bluestripe® These precision ground tooth blades have a patented solid-state diffusion process which produces the industry's most advanced bi-metal hand hacksaw.

How well would this cut an aluminum hand guard on a paintball marker?

I've cut through steel with these blades. As long as the metal on the hand guard is not thinner than 1/32", and the correct technique is used, there should be no problem.
