The items in the picture are arranged on shelves. A shelf is a “A flat, rigid, rectangular structure, fixed at right angles to a wall, and used to support, store or display objects”. Terms like tray and rack may also be appropriate for the shelves.
The whole structure is (as Mari-Lou mentioned) a display counter, but might also be called a display case, and if it had a glass front, a vitrine, “A glass-paneled cabinet or case, especially for displaying articles such as china, objets d'art, or fine merchandise”.
To avoid used of display as a noun or adjective and as a verb, consider the verbs held and arrayed:
At the front, a display case held all kinds of sushi.
At the front, all kinds of sushi were arrayed for sale.
All kinds of sushi were arrayed for sale on shelves beneath the counter.
There is a specific name for it: pandiculation.
A stretching and stiffening of the trunk and extremities, as when fatigued and drowsy or on waking, often accompanied by yawning.
Joseph Ducreux pandiculating; self-portrait ca 1783
Note: While stretching is more common, it is also more general. OP didn't specifically asked for a common word and there are details in the question. Pandiculation is a tailor-made word for this specific movement. At least, you learned a new word if you didn't know it.

It's a battlement or crenellation. This consists of a parapet (a short wall on top of a roof) with cops or merlons (the solid parts) and crenels or embrasures (the parts you can look through or fire arrows through).
Those links are all to Wikipedia, which I know you might not consider a reliable source (although all of those articles contain references). So, here's the Oxford English Dictionary's definition of battlement:
Also, you can read the entry for battlement in the 1911 edition of the Encyclopedia Britannica. You can also take a look at a page all about parts of castles in the Middle Ages for some related vocabulary.
