I am part of a group of people that sings in the Church. We don't have nobody that knows how to play those musics in the guitar because we can't find the strumming pattern.

I have here some of the music played in the guitar but I still can't find the right rythm. If someone could help us.
The musics are:

1 -

2 -

3 -

4 -

5 -

6 -

7 -

If someone could help us. We have a certain urgence in this...thanks
