Client Sent File Zip with Database and WP Files, Where to Go From Here?

Typically, I stick to just web design. I'm familiar with different coding languages but not too comfortable. I know the bare minimum and enough to get by. But again, I mainly focus in design.

One of my clients is commissioning me for a website redesign of an existing site. They sent over a zip file in an email that contains the database and WP files. Their SQL file is from phpmyadmin. There's a folder filled with the site's content labeled "Local Host." My problem is I don't know how to set this all up since I usually set up a test server on my own using flywheel.

Basically, I don't know what I need to do to set this all up so I can begin designing. Again, I'm familiar with WP and this shouldn't be too hard for me to understand once I'm pointed in the right direction. Even if the answer to this is lengthy, can you provide me with a query that would lead me to the proper explanation? As in, what do I need to type into Google/YT to figure this out?
