When I clicked Alt and select the face its select all the faces in the horizontal direction , which is not not what I required I want to select the faces in the vertical direction. Is there anyway to do it. In other software I can shift select two faces and the faces in between automatically gets selected. How can it be done in Blender?
To choose the direction the loop select will go, you should be in face selection and alt select an edge in the direction you want the edge loop to go. If you want it to go vertical then alt select the top edge while in face selection.
