Q: how many gospel again ?

A: there is one gospel and that is gospel of God

   - but in this one gospel of God there are many gospels, such as

1. gospel of the kingdom (Matt 4.23)

2. gospel of the Lord Christ (Mark 1.1)

3. gospel of God (Mark 1.14)

4. gospel of peace

5. gospel of grace (Acts 20.24)

6. gospel of salvation (Eph. 1.13)

7. gospel of the cross (1 Cor. 1.18)

8. gospel of the Eternal (Rev. 14.6)

* every gospels are for the gospel of the kingdom since it is the will of God and the Lord also commands us to seek for this kingdom(Matt 6.33), sadly only a few fins it (Matt 7.14).
