The answer to your question is contained in the UGC Regulations, link to which is given by you, Regulation 1.2 of which states as under:
“They shall apply to every University established or incorporated by or under a Central Act, Provincial Act or a State Act, every institution including a constituent or an affiliated College recognized by the Commission, in consultation with the University concerned under clause (f) of Section 2 of the University Grants Commission Act, 1956 (3 of 1956) and every Institution Deemed to be a University under Section 3 of the said Act.”
Therefore, provisions of these Regulations will apply to all Universities and all institutions recognized by the UGC and also in all institutions which are deemed Universities.
If such regulations are to be applicable to any other organisation, then there has to be a specific provision or order to that effect. So, you’ll have to check from the NCTE whether these regulations are applicable to them. File an RTI application, if needed.
These Regulations clearly mention that they are applicable to OBC also.
For your third question, seek information from the concerned agencies, if necessary by filing RTI application.
