Is the 7/8-inch an inside diameter or outside diameter ?

the outside dimension is 1/2". I am uncertain where you referencing 7/8".

The dimensions on this spring are .05x1.5x3.8 in. Where does the 3.8 apply?

I don’t know where the 3.8 came from but the title says “1/2 inch by 1-1/2 inch -.041 diameter” The .041 applies to the diameter of the wire itself

Would a m5 screw fit in it?

A 5mm screw can fit but it will depend on what diameter the head of the screw is if you wish that part to fit inside.

What's the compression rate on this spring? (How far does it compress with a 1-pound weight)

Without actually measuring, it will probably compress half way. It is a wire wrap spring and not a high-strength alloy.
