When there are particles, reflexive verbs with prepositions and negation how are the words in a sentence is formed? Also lets assume that both the place and the time is stated in the same sentence. Is there a particular rule, as a novice German learner I confuse it a lot?
No there's not one rule. There's a bunch of tendencies that are more or less robust. But as soon as it comes to the negative and to where to put place, time, and objects it also depends on what form these elements have. A "place-pronoun" will likely have a different position than its spelled out counter part.
Ich treffe mich mit Maria im Park. (natural)
Ich treffe mich mit Maria da. (less natural)
You need to get a feel for this. As a novice learner you cannot expect to get everything correct. It's simply impossible. If you want a detailed look on word order, you can check out the mini series on my blog.
