N,o that won't be an issue , and also all government jobs are selected via UPSC or other similar exams.

I am not sure which university you were part of, but 5 years to get an original certificate is too much. If the university is not providing you after multiple requests, you can initiate legal action against them. If you have lost the certificate, you might have to register an FIR, and also put an ad in a local newspaper before requesting for the re issue of the certificate. But any way contact your University to understand the procedure.

No, there is no problem at all in your improvement examination. Contact your regional head Office for clear and accurate knowledge about examination. Hope it will help you.

You have not specified the name of the institution you want to take admission into, but if the admission criteria has mentioned at least 60% then you are required to have that much for admission.
