You can use them in a casual way (daily conversation). These particles are used simply to show emotional expressions.
● Sih = just like the English "really?" it can be used to emphasize the question or to express disbelief or annoyance.
For example:
Masa, sih? (really?)
Nggak juga, sih. (not really)
Or sometimes it can be like this:
Ngapain, sih? (what are you doing, actually?)
Maunya apa, sih?! (what the hell s/he wants, actually?!)
However, "sih" has lots of meaning depends on the context and tone.
● Nih = a slang form of "ini" (this), while Tuh is a slang form of "itu" (that).
● Kok = to make sure about someting.
Example:
Dia baik, kok. (don't worry, he's a nice person)
Deh, Dong, Lah, Lho = most of these particles are only used to emphasize. But sometimes it can be meaningless too.
