I have 2 string cells arrays (a 1 X 191 cell array and a 5 X 1 cell array). How can I concatenate the two so I have a 955 X 1 cell array that starts with Raw intensity mean (191 times), Gray mean ws=3 mean (191 times), etc. for all 191 cells.

What you need is the Cartesian product of the two sets. MATLAB does not have built-in function, but there are several functions on FEX.

I noticed how the inputs must be numerical vectors. Can I still use this?

You can have it work for strings by editing the function. For example, you change
X = zeros (...);
to
X = strings (...);
I think no other change is needed. Or you can use another FEX function.

As I mentioned, there are several functions for this on FEX. You can get them by googling "matlab cartesian product".
