I can't seem to wrap my head around what these catalysts are and how to distinguish if a catalyst is homogenous or heterogenous so if anyone can help explain I would really appreciate it.

I also have a question on it:

A solid catalyst, Vanadium (V) Oxide, V2O5, is used in industry to increase the rate of production of Sulfur Trioxide, SO3, in this reaction.

2SO2 (g) + O2 (g) -><- 2SO3(g). ( -><- means reversible reaction)

Explain, with a reason, whether V2O5 is a homogenous or heterogenous catalyst.

Homogeneous means that the catalyst and the products/reactants are in the same chemical state or phases (solid/liquid/gas). Heterogeneous means that the catalyst and the products/reactants are in different chemical states or phases. Look at the information given in the question and you should figure this out c:

So its Homogenous since they are all gases?

You're looking at the balanced equation, which doesn't include the catalyst. The answer is in the bit above the equation.
