麻煩幫我睇睇文法有無錯吖!TKS!!!

Your sentence is a bit long. Remember, simple sentence always makes understanding easier.

Try to divide the original sentence into two and take away unnecessary words and phrases.:

1)Please inform our PRC team members who in the attached name list to Finger Print.
Mistakes/changes:
who in the attached name list - who ARE ON the attached name list--take who are away, just write 'on the attached name-list'
Finger Print- no need to use capital letter, to do finger-printing.
Correct sentence:
Please inform our PRC team members on the attached name-list to do finger-printing

2)We also will post this notice to our Dormitory and just in case if they miss it.
Mistakes/changes:
also will - will also
post to our dormitory- post on our Dormitory door張貼在宿舍門上
and just in case if - take and, just , if away -- just in case
Correction sentence:
We will also post this notice on our Dormitory door in case they miss it.


ANSWER:
Please inform our PRC team members on the attached name-list to do finger-printing. We will also post this notice on our Dormitory door in case they miss it.
