can you use an imoact driver instead of drill whit this

No, it’s not for the impact drill.

What rpm is recommended on granite?

Slow and with a water well around where you want to drill the hole.

What's the maximum depth of the cut?

Slightly more than 1", depending on material and chip clearance.

Would a 18v 2100rpm brushless RIDGID work for it to drill a concrete wall?

I used a Ryobi 18v to drill thru granite, so I would assume slow, going slow. However I would test it on another piece of concrete if available. Also, it would be wise if drilling thru concrete to purchase several as the diamond edges would wear out.. remember, slow and add water to cool the bit. Good luck..
