You have not given details of the Supreme Court decision (such as case No. or party names), but it appears that you are referring to the decision of the Supreme Court at this link, which I have covered in a similar reply earlier that can be seen at: Regarding decision of Supreme court on deemed University.
If the Supreme Court has suspended / cancelled only the Engineering degrees awarded by certain deemed universities, then of course, other degrees awarded by these universities would not be affected at this stage.
Time period for filing review petition in Supreme Court is 30 days. However, you can file an application for condonation of delay, if you can explain the delay due to some genuine reasons.
Whether petitions can be filed in lower courts in a certain matter would depend upon the facts of the case, the type of issues involved, the remedy sought, etc. In general, writ petitions can be filed against such degrees in the high courts (under Article 226 of the Constitution) or in the Supreme Court (under Article 32 of the Constitution).
