Dear Chulantha, your question is too general. Contact your local mite expert, check the Krantz & Walter Manual. Organize your material by families and after look at the Manual for references.

There are many references of different groups of mites for identifying the species. But at the first step, as Ron mentioned, you should determine their higher taxa. Have you ever identified the orders, suborders or families of your mite? Where have you collected your specimens, from plants, in soil, litter, on insects, ...?
Some of the mites I collected from insects and some from fresh water. Here, we currently don't have anyone working on mites. I was looking for proper identification keys to put them at least into their families or Genera. I Just started to work with mites so I don't have a strong grip yet.
Last year I was identified soil arthropods from litters together my colleague. In our observation, I found Collembola, Coleopteran and etc (please find my attach file). I hope you satisfied.
Do you have the Krantz and Walter manual? Base on your comments several families could be present of water mites, and on insects very different groups Mesostigmata, Heterostigmata, Acaridae. Take good pictures of the mites under a stereoscope microscope for the water mites, and for the other mites a good microscope with DIC and Phase contrast, as one of the families associated with insects (on beetles, orthoptera..) are the Podapolipidae and there are tiny.
