Read the three images into your script (the images have to be saved in your working directory so your code can find them)
Resize the images to be the same size using imresize
Duplicate both of the images and change the RGB values in a way that you like.
Concatenate the original and recolored images however you would like - 6 images total
Display the collaged image in a figure and add a title

Here is my code and I don't know what is wrong with it. Please help me! Thank you in advance.

% Read three images into script

image1 = imread('Cross_Image.jpg');

image2 = imread('Monkey_Image.jpg');

image3 = imread('Nature_Image.jpg');

% Resize three images to be same size

image1 = imresize(image1, [213,413]);

image2 = imresize(image2, [213,413]);

image3 = imresize(image3, [213,413]);

% imshow(image1)

% imshow(image2)

% imshow(image3)

% Duplicate three images

image11 = imread('Cross_Image.jpg');

image22 = imread('Monkey_Image.jpg');

image33 = imread('Nature_Image.jpg');

% Resize three altered images

image11 = imresize(image11,[213,413]);

image22 = imresize(image22,[213,413]);

image33 = imresize(image33,[213,413]);

% Alter three images

alteredimage1 = image11(:,:,3) + 15;

alteredimage2 = image22(:,:,2) + 53;

alteredimage3 = image33(:,:,2) + 10;

% Show three images

figure;

imshow([image1 image2 image3]);imshow([alteredimage1, alteredimage2, alteredimage3])

Try putting the altered images in the row below the originals.

imshow([image1 image2 image3; alteredimage1, alteredimage2, alteredimage3], [])

When you do this

% Alter three images
alteredimage1 = image11(:,:,3) + 15;
alteredimage2 = image22(:,:,2) + 53;
alteredimage3 = image33(:,:,2) + 10;

You're taking only one color channel. If you want to alter only one color channel you have to initialize altered images.

% Alter three images
alteredimage1 = image11;
alteredimage1(:,:,3) = image11(:,:,3) + 15;
alteredimage2 = image22;
alteredimage2(:,:,2)  = image22(:,:,2) + 53;
alteredimage3 = image33;
alteredimage3(:,:,2) = image33(:,:,2) + 10;
