How many devices that genymotion SaaS provides?

Genymotion SaaS does not have one fixed number of devices for everyone. The simultaneous device limit depends on your subscription plan, and the free trial gives 2 simultaneous devices for individuals or up to 10 for companies. See How many devices can I run simultaneously? and How do I get the free trial for Genymotion SaaS Cloud?.

You can create as many recipes as you need, but only the number of running devices is limited by the plan. On the Pay-As-You-Go plan, the default limit is 2 devices simultaneously.
