Under what conditions?
Most metals at ordinary conditions (those you might find in, say, your living room) are solid and "gray" (if your definition of "gray" includes silver). A lot of the semi-metals/metalloids are also. Iodine isn't a metal or a semi-metal, but it's solid and sort of gray at those temperatures and pressures anyway.
The metals that aren't solid and gray at STP:
Mercury (liquid and silvery)
gold (solid and ... well ... gold)
copper (solid and reddish-orange)
caesium (solid, but melts just above room temperature, and it's a very pale yellow color)
bismuth (solid with a very faint pinkish tinge)
Also, a lot of metals tarnish with exposure to air and form a thin (or not so thin) layer of the metal oxide (or sulfide, sometimes). This layer may make the metal appear to be some color other than the pure element (for example, bismuth forms a surface layer of oxide, and depending on the thickness it can be just about any color from deep pink to blue).
Niobium is a solid. It is a silver-gray metal that is typically found in the solid state at room temperature.
Elements that are not silver-white, silver-gray, or dark-gray in color include sulfur (yellow), copper (reddish-brown), gold (yellow), and potassium (silvery-blue). These elements exhibit a range of colors due to their unique electronic structure and the way they interact with light.
Calcium exists as a soft gray alkaline earth metal in its natural state. It is the fifth most abundant element in the Earth's crust and is commonly found in minerals such as limestone and gypsum.
Chemical elements may be solid, gas or liquid.
Protactinium is a solid state of matter. Specifically, it is a dense, silvery-gray metal that is radioactive.
Cerium is a soft gray metal of the rare-earth group of elements. At room temperature it's a solid.

Some examples of solid elements include iron, gold, carbon, silicon, and sulfur.

solid compounds. When pure still solid and mainly metallic
yes it and airplane
solid gas
No there solid liquid and gas
Out of the first 18 elements on the periodic table, 10 are solid
