Merge Three Photos Side-by-Side

I have two separate photos—one featuring two people and one photo with one person —that I’d like to turn into a single image. The final result should simply place the subjects side by side, preserving every individual’s original background exactly as it appears now. No color grading, skin retouching, or other edits are necessary; a clean, seamless composite is all I need.

Please deliver a high-resolution JPEG and the layered source file (PSD or equivalent) so I can make minor tweaks later if required. Let me know if you need any specific dimensions or additional info from me to get started.
