one of my cuttings have roots on every join , how should i plant this?
should I put it up right, half in the soil and the other half sticking up? or should I put the whole thing horizontal under the soil?

Any of those methods will work. I had several from Jon this year that did exactly the same thing and I tried each method. When I planted it normally, it shed the roots above soil level and out came the leaves. The one I planted sideways still hasn't gotten any green but I took it out yesterday because I thought perhaps it had dies, no it didn't but it did fill up a 1 gallon container with roots. The third one I put mostly in the soil with the tiny tip sticking up and again, the roots are insane but no greenery yet.

I'm okay with that because right now I am more concerned with the roots anyway.

I think my favorite way was the tiny tip sticking up.

I also have some logs I got from Kerry and they will be going in sideways.

I hope this helped even a little.

if I bury it sideways, will it grow as a bush , or it doesn't matter?

I don't know the answer to that one. I know Tim told me to dig up the logs next winter and cut them in half. 

Just plant it the correct side up. The bottom will keep growing roots while at the top they dry out and the leaves will appear. I had a similar problem, please see here what I have now:  http://figs4funforum.websitetoolbox.com/post/What-the-...-6254463
