My files are in 1 folder which I set in Matlab as my Current Folder. The names are: g1, g2, g3, g4, g5, g6, and so on...
Currently, I'm importing using the code below.
h1 = csvread('g1.csv', 9, 0, [9, 0, 10008, 8]);
h2 = csvread('g2.csv', 9, 0, [9, 0, 10008, 8]);
h3 = csvread('g3.csv', 9, 0, [9, 0, 10008, 8]);
h4 = csvread('g4.csv', 9, 0, [9, 0, 10008, 8]);
h5 = csvread('g5.csv', 9, 0, [9, 0, 10008, 8]);
h6 = csvread('g6.csv', 9, 0, [9, 0, 10008, 8]);...
It works, but I know there has to be a way to loop this function. Any ideas on a simple for-loop to complete this task?

I'm trying to do something like this.
for (i = 1:10)
csvread('g(i).csv', 9, 0, [9, 0, 10008, 8])
end

See code samples in the FAQ: https://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
There are two ways there depending on what order you want to sort them in and if any files are missing.

I read the link, but can't follow. I'd like to do something like this:
for (i = 1:10)
csvread('g(i).csv', 9, 0, [9, 0, 10008, 8])
end

Well you can't. You have to use techniques such as are described at the link that was posted.
for (i = 1:10)
csvread( sprintf('g(%d).csv', i), 9, 0, [9, 0, 10008, 8])
end
