Image/content obtain consistent sizing

Hey all, think this one is pretty simple but just can’t figure it out for the life of me…

On the homepage, second section down underneath the demo form I’ve created some new content called “Video Testimonials” that I am currently working on. My question is - what do I need to do to ensure the images and 4 sections stay the same size? At the moment the shapes/sizes are being distorted and determined by the length of the text (e.g. Bryce from Fishbowl).

I have the same issue with the images on my FAQ section (the arrow and minus sign) being dictated by the length of the FAQ title. More noticeable on smaller mobile screens.

Help is greatly appreciated
