Well, you asked :)

16:00 - "четыре часа"
16:10 - "десять минут пятого"

16:15 - "четверть пятого"             / equally used
16:15 - "пятнадцать минут пятого"     \ equally used, note usage of "минут" here...

16:30 - "половина пятого" - more official and long,
16:30 - "пол-пятого" - spoken language, short and _really_ fuzzy :)

16:45 - "без четверти пять"   / equally used
16:45 - "без пятнадцати пять" \ equally used, but no "минут" here...

17:00 - "пять часов"

see also the difference in "часа" and "часов" - different plurals.

(same expressions refer to 4:00, 4:10 etc. in the morning, if one wants
to distinguish also daytime, things become more complicated).
