All upright type pianos are vertical pianos. All horizontal pianos are grands. The smallest vertical is called a spinet then, console, studio and upright. There is no such thing as an "upright grand." It is just a name placed onto a piano.
There are two main types of piano - upright, in which the strings are set vertically, and grand, in which the strings are set horizontally.
On a standard upright or grand piano, there are 88 keys.
An "upright grand" piano is simply a big old upright piano. The term was common in the early part of the twentieth century and was intended to infer a sense of higher quality than the rather ordinary term "upright piano" (and was often used by manufacturers of lower quality instruments). "Cabinet grand" was a similar term applied to upright pianos. I think the bass strings of an upright grand are longer than in plain upright.
Grand and baby grand- grand piano's are favoured by professional pianists because they think they give a better, purer tone, although a really high quality upright piano can sound almost as good. A 'baby grand' is just a half-size version of a full-sized grand.
Before 1800, all pianos were grand pianos that required a lot of space, but that year saw the development of the John Hawkins' Portable Grand Piano, the precursor of the now-familiar upright piano.
