Great questions, Nirzhar.
The dataset covers #1 (age) and #5 (resources used). Free Code Camp explores them here (they only report the median age, but I included a histogram for a subset of the survey here).
#3 wasn’t asked. I don’t think #2 and #4 can be answered in the level of detail that you specified, but there is some data on those already employed and prior education (same FCC link as above).
