New to bamboo, lots of q's

Hi, we have just been given some bamboo, the picture below shows them in
the garden.

[image: http://img.photobucket.com/albums/v733/stevebrum/bamboo.jpg]

q1) Can anyone tell from the picture what type they are?

q2) Are they too close to the fence?

q3) Will they grow quickly to above/fence height

Thanks
