water is an element, instant coffee powder is a mixture, combined it is still a mixture.
Water and instant coffee is a homogeneous mixture, specifically a solution, because the instant coffee particles dissolve evenly in the water forming a uniform mixture. It is not an element, as elements are pure substances made up of only one type of atom.
That would be a heterogeneous mixture as there would be small particles floating in the water.
A drink of coffee is a compound because if you took a sample from anywhere in the cup, that sample would have the same chemical formula as any other spot in the cup. If there were spots in the cup that had excess substances such as coffe grounds it would be a mixture. Also since coffee is made up of several things, eg) coffe grounds, water... it is obviously not an element. Therefore it must be a compound.
Coffee with cream is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the original mixture.
Coffee is a heterogeneous mixture. Its main composites are water and refined coffee beans which can be mechanically separated.

It's a mixture
Heterogeneous mixture.

In chemical terms, instant coffee is defined as a mixture since it contains many different molecules as coffee is a plant that uses millions of different molecules. A substance is usually taken to mean a compound in chemistry.
It would be a heterogeneous mixture because of the little coffee grounds floating around. It's not uniform throughout.

Neither, it's a mixture. More specifically, a solution or homogeneous mixture.
