I start working with Spring and have some confusions about its conventions.
Services and other Reposities?Service And Repository class is based on Entity name i.e: User -> UserRepository->UserService?

According to documentaion @Repository , @Service , @Controller are all synonyms. They all are just specializations of @Component annotation. So, generally, they can be used one instead of other.
@Service annotation is used with classes that provide some business functionalities. @Repository Annotation is used to indicate that the class provides the mechanism for storage, retrieval, update, delete and search operation on objects. @Service Annotation is a specialization of @Component Annotation.
@Component is a generic stereotype for any Spring-managed component or bean. @Repository is a stereotype for the persistence layer. @Service is a stereotype for the service layer. @Controller is a stereotype for the presentation layer (spring-MVC).
@Component is a generic stereotype for any Spring-managed component. @Service annotates classes at the service layer. @Repository annotates classes at the persistence layer, which will act as a database repository.
No, don't use Repositories in the Controller. Only in the Services. And don't use Entities in your Controller. Create Dto (Data Transfer Objects) Object from the Entities and work with this in your frontend
Yes you can use other services and respositories in your service class
Yes it is. Name the interfache UserService and the implementation UserServiceImpl
