Answer 1

I suppose you also have

User
   UserID
   Name

Then you can type something like this

from user in Users
where user.UserServices.Any(
   userService => userService.Service.Any(
       service => service.UserServices.Any(
           userService2 => userService2.UserID == 5)))
select user
