That is around the theoretical maximum yield of alcohol without being denatured. And by alcohol I'm assuming you mean ethanol (drinking alcohol), so the only uses would either be drinking (but I would not recommend doing this) or maybe fueling a car or some other vehicle that has been converted to work using alcohol as fuel. (but i believe even to fuel vehicles you need 100% alcohol which would require denatured ethanol using methanol.)
P.S. - if you plan on drinking alcohol that is 95%, and if so I'm not going to ask where you got it because it isn't legal to sell in the U.S., please do not do so without WATERING DOWN the beverage. Because it only takes somewhere around several hundred milliliters of pure ethanol to kill someone [and in case you didn't know a fifth of hard alcohol is only 750mL], which isn't very much.

One has 4.5 percent more alcohol which is important because you can get to a max of 95 percent using fractional distillation. To get the 99.9 percent or absolute alcohol, you need to use other more advanced methods. Some of these include include desiccation using adsorbents.
70% alcohol means in hundred parts of it, 70 parts are pure alcohol, rest is water. 95% means 95 parts of pure alcohol in 100 parts, so 5 parts of water. It depends on the usage. As a solvent, 95% would be preferred. As antiseptic, both can be used, 75% being more common as medicinal spirit. For consumption, fairly dilute concentrations are preferred. Above 43% are rare so both the above concentrations are dangerous for consumption.
