The 4s and 4p wave functions of Be³+ are degenerate. Yes, this is true for hydrogenic atoms such as Be(3+). No, this is false for multi-electron atoms such as Be(3+). Yes, this is always true since 4s and 4p functions have always the same energy. No, this is always false since for all types of atoms 4p has always higher energy than 4s.
