using 'with respect to'

Is this correct way to use "with respect to"???

Yes.

The definition of this phrase is "concerning or in relation to something".
"Respect" here means "reference" or "relation".

You are using an abbreviated style of speech that appears in certain circumstances such as the subject line of emails or headlines. A full sentence would be:

The attached files contain all the details with respect to our meeting and the RFI's raised by the contractor.

It's your decision if you'd prefer to use the abbreviated style or not.
