Left Hand lever should be slightly taller - that one is for the front axle engagement.
It should have two positions:
Aft = front axle engaged.
Forward = Front axle NOT engaged.
Right Hand lever is the Range selector, with three positions:
Forward = Low range reduction.
Middle = Neutral - no drive to either axle.
Aft = High range - 1:1 ratio for normal street/highway use.
The linkage in the T-Case should have a built-in interlock that does NOT allow 2WD Low Range.
Therefore you have four (4) drive options:
2WD High Range
4WD High Range
4WD Low Range
Neutral (no drive, regardless of main transmission position))
Typically, there are decals installed either on the dash or glovebox door that illustrate the transmission/transfer case shifting positions.
The lever with the latch handle is the parking brake as noted previously.
