How would I know that it is alright to run more than one instance of Tor?
VPS providers usually don't restrict how many processes you run. Some don't like if you use too many resources, as overselling is part of their business model. But how would I know? When in doubt, ask. In general, don't push it too hard. You get what you pay for, and you can't expect to get unlimited resources for the price of a donut.
