If you are storing these values as strings then the results you see are correct. They should be stored as DateTime types so they are sorted according to their time value.

You can do something like this, but I would rather suggest you to look at you database design and store the value as proper types instead of string values.

CREATE TABLE #Timings (START NVARCHAR(100), ENDS NVARCHAR(100), Timing NVARCHAR(100))

INSERT #Timings
SELECT 
	SUBSTRING(Timings, 1, CHARINDEX('-', Timings) - 1),
	SUBSTRING(Timings, CHARINDEX('-', Timings) + 1, LEN(Timings)),
	Timings
FROM 
	FacultyTiming 
ORDER 
	BY Timings

SELECT 
	Timing
FROM 
	#Timings 
ORDER BY 
        CONVERT(time , START)

DROP TABLE #Timings
