Colossians 2:9 (DARBY):
For in him dwells all the fulness of the Godhead bodily.
What is meant here by Godhead?
Does Godhead composed of Father, Son and Holy Ghost (Holy Spirit)?

I suggest you think of the term Godhead as personhood. As commenter davidbrainerd observed, an ME variant is godhood.
We might, for example, say of someone:
"She is secure in her personhood."
In other words, she is confident in who she is as a person--her personality, temperament, strengths, weaknesses, physical and intellectual attributes, and so on.
In the Godhead, according to traditional Christian thought, there are three persons, each of whom share the same personhood. When I think of God, very often I think of God the Father. What Paul is saying by implication in Colossians 2:9 is that Christ shares fully in all of the attributes of the Father.
While the passage in question does not mention the Spirit, from other passages throughout Scripture, the Holy Spirit, too, shares in all the attributes of divine personhood.
According to Christian doctrine, going back to--at least--the Nicene Creed of AD 325, each Person in the Godhead is truly God, since God is of one essence, but each Person has a unique role to play in redemptive history and beyond. When Paul says that in Christ all the fullness of the Godhead dwells bodily, he is saying that Christ is of one essence with the Father and the Spirit. Or put differently, each person of the trinity is fully God.
I'm perhaps oversimplifying here, but I proffer the following in conclusion:
The Father delegates authority (1 Corinthians 15:27-28); the Son exercises that authority (ibid.); and the Holy Spirit reinforces that authority with His power. Through that power the Spirit reveals the Son and brings to believers' remembrance all that the Son said (see, for example, John 14:26 and 15:26).
