Regarding the tense, shall I say the action of past tense happens later than those of present perfect tense.
eg. I went back home after my mum has just got back from Japan.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
1) Sorry, I get confused in under what situations shall
a) past and present perfect tenses appear in one sentence?
b) past and past perfect tenses appear in one sentence?
c) present and present perfect tenses appear in one sentence?
2) Shall I say:
a) I put my hands on my laps.
b) I put my hands in my laps.
3) Shall I say lap or laps in the question 2)
The above are not homework but they have been a big question mark in my mind for long.

"I went back home after my mum has just got back from Japan."
In this case, each clause makes sense, but if you think about what they mean, you can't put them together.
The present perfect in the last clause is a present tense. It says what has just happened - what is completed in the present. You can't therefore say that you went home after it, because it has just barely happened.
It might be useful if you tried to answer question 1. yourself, and post some sentences in those tenses which you think make sense.
You should start a new thread for further questions. Your first question is complex enough, and hasn't been answered yet. The thread can only go downhill if people start answering bits and pieces of your post. (Anyhow, I'll dispense with it: You say 'lap', and you can use either 'in' or 'on'.)
