Learn English – What are the machines at the grocery store entrance called

A little shop set up by the road side (and roofless, or with a tent-style roof, or in a cart) is known as a street vendor. They are very common in large cities. I found a good link defining this: What Is a Street Vendor?. Quoted from this source:

Street vendors are businesspeople who sell their wares in the open air rather than in a shop or store. In many cases, the vendor either has a small stand that can be secured when not in operation, or makes use of a cart that can be removed from the street at the end of the business day. Sometimes referred to as a peddler, the street vendor is commonly found in metropolitan areas, outdoor conventions and events, and sometimes at public beaches.

As a counterpoint to Kevin, I have heard non-Jeep branded vehicles that are of the same 'format', called "jeeps" (and in fact, would have used that word myself for the top two images). I would not use SUV for the second image as I generally think of SUVs as more of a full-size enclosed vehicle (e.g. a Tahoe or Navagator), although it obviously is a "sports utility vehicle".

The third picture I agree is a van, although a very foreign looking one.

For reference, I'm from and currently reside in the Southeastern US, but have lived in the Midwest and Northeast.
