1. They can re-appear in some occasions. There's no definite schedule for certain limited SSR's though, but there's always a limited  SSR Servant apperance during New Years (JP)/Thanksgiving (in NA) and F/GO anniversary.

2.  The limited Free SR servants, ..some do have time limit on them, that is, if you didn't finish the main story quest, they'll be not staying with you and you have to wait till next year to get them again, but don't worry they give you a lot of time to get them.
