What does mean or why we write the letter "o'" with clock? Is there any letter instead of the apostrophe?

O'clock is a historical contraction of of the clock.

This o' contraction for of also shows up in:

jack-o'-lantern, will-o'-wisp/will-o'-the-wisp, cat o' nine tails, ...

This isn't a very productive contraction though.
