You can use Rogue Miner to mine all SHA256 and Scrypt based currencies. This mainly refers to BTC, LTC, BCH and DOGE but you can make a simple search to know if a given currency uses one of those algorithms and can be mined with this miner.

The number of computers where you run this miner is not as much important as their tech specs. That's the only parameter that you need to know if you'd like to estimate your earnings.
