That's the purpose of the sextant.
There are several ways in which you can determine your latitude. 1. Use a GPS unit. It will read out your latitude, longitude and precise time. 2. Look on a map; most navigational and topographic maps are scaled in latitude and longitude. 3. Radio navigation beacons like LORAN or R_NAV can give you your latitude. 4. At night, and in the northern hemisphere north of about 15N, you can (weather permitting) take a celestial observation of the north star Polaris, and the sextant reading is, with a half-degree or so, your latitude.
You find the lines of latitude and longitude and find the place that they intersect, which is your location.
Yes.

A backstaff is a an early navigational instrument for measuring the altitude of the sun and hence calculating latitude.
It's not necessary at all. But the fact that it can be usedas a navigational tool makes it quite useful.
Navigational tools such as maps and compasses are essential for hikers to find their way through the wilderness.
