I want to know how to put 3 images in one row in Latex, so that it looks like the following format:
Anyone can help me! Thank you so much!
Note: The figures need to span two columns inside a multicols environment.

Images can be included from anywhere if you specify the path. Something like \includegraphics{./images/Chap1/figure-name} should be fine, assuming that the images folder is a subfolder of the one containing the TeX. Does that answer your question?
Since all four subfigures must appear on one row, the total width for the subfigures must not exceed \textwidth; you could use .25\textwidth (at most, if they all have to have the same width) for each subfigure and make sure there's no spurious blank spaces between them (notice the % characters after the three first \end{subfigure} lines).
Below you find two possibilities using the maximum width for each subfigure; in the first case, the width of the image equals the width of its container (and the images will appear without space in between); in the second case, the width of each image is a little smaller than the width of the container, so there's some air between the images.
Notice that in the first case, the subfigures are taken all the available width and each image takes all the available width inside its container too, so there's no need to use \centering there.

Of course, you don't have to give each subfigure a width of .25\textwidth; you can use a smaller value (in this case, \centering will be needed) and you can use some space, (an explicit space, or \quad, or, even better, \hfill) to separate your figures:

Here's how to position figures across the columns of
multicol:Note that I'm using the starred version of the
figureenvironment. The[ht]tag specifies position, here indicating "at the top of this page." Google "LaTeX Floats" for how to change that and how to adjust thefigureenvironment.Here: copy\paste only this part:
