Yes they are. They would not be allowed to fly if they were not deemed safe. Some airlines companies from the third world for example, are banned from flying in Europe and not considered safe. Ryanair has never had any accidents either. They may be extremely annoying since they are a low cost company and will charge you like crazy if you mess up with check-in or bring overweight baggage, but safety wise, you can relax. It is also said that Ryanair pilots are quite good at landings, as they usually use short runways which takes more skills :)
