Leo, Randy's answer is very good, and he is right, the verb get has many different uses.
I hope you're interested to read and learn the different ways to use the verb "get", because I copied and pasted an excerpt from great English Usage book that I recommend to anyone learning English.
I'm a native English speaker. My vocabulary is over 100 words (that's a joke). But I have learned many things from this book:

Get is one of the most common words in English, and is used in many different ways. It is sometimes avoided in a very formal style, but it is correct and natural in most kinds of speech and writing. The meaning of get depends on what kind of word comes after it. With a direct object, the basic meaning is 'come to have'; with other kinds of word, the basic meaning is 'come to be'.
1 get + noun I pronoun
With a direct object (noun or pronoun), get usually means 'receive', 'fetch', 'obtain', 'catch' or something similar.
I got a letter from Lucy this morning.
Can you come and get me from the station when I arrive?
If I listen to loud music I get a headache.
If you get a number 6 bus, it stops right outside our house.
Get can be used with two objects (see 583).
Let me get you a drink.
Other meanings are sometimes possible.
I didn't get the joke. (= 'understand')

Could I get ... ? is not generally used to order things. Compare:
Could I have a coffee? (= Please bring me one.)
Could I get a coffee? (= Could I make/buy myself one?)
Get + noun/pronoun is not normally used to mean 'become'. Get to be ... is common with this meaning (see paragraph 6, below).

Before an adjective, get usually means 'become'.
