Are they green olives or black olives?
Green and black olives on the same branch
That's a matter of ripeness. All olives left on the tree will eventually ripen to black. Olives can be pickled at any stage of ripeness. "Green ripe olives" are picked at a certain stage of development, when the juice inside turns from clear to milky. Olives to be used for oil are usually left on the tree until at least some color change has occurred. "Black ripe olives" can be ripened on the tree or picked green and turned black in processing, as with "California Black Ripe Olives." See the link below at the question "How do I process the fruit?" for recipes for home processing of olives.
Do your trees make table olives or oil olives?
Wherever olives are grown, almost any cultivar of olive is used for both table fruit and oil. References to a particular cultivar's purpose is generalized and refers to the primary commercial purpose of the cultivar. The exception to the rule is a few cultivars that produce very little oil and so are generally used only as table fruit. A large percentage of the Egyptian cultivars fall into this category.
How long before I get fruit?

That is a function of cultivar. 'Arbequina' and 'Koroneiki' begin fruiting at an early age (about 3 years). Other cultivars do not make fruit until they are five to twelve years old. Most olive cultivars will not produce fruit without a pollinator tree of a different cultivar. There are also non-fruiting cultivars of olive. Olives grown from seed may never produce fruit and, if they do, will not likely have the same characteristics as the parent tree.
How do I process the fruit?
Olives soaking in brine
Olives are ripe enough for green pickling when the juice inside is cloudy instead of clear.
The following article from the University of California at Davis describes some of the many ways to process both green and black ripe olives at home:
