Do KLM will permit to board aircraft at Delhi Airport as they will have two different PNR ticket on KLM and one ticket on Surinam Airways.
No.
For KLM, they are transporting you to Amsterdam, and you (the traveler) need to show proof that you are able to be landed there.
As far as KLM is concerned, you are not in transit.
Do they will face any challenge on their check in baggage ...i mean can the baggage be tag till Curacao as both will be same carrier even though issued on separate PNR/ticket.
As you are only being checked in on one flight (DEL - AMS), your bags will only be checked through to AMS. You will have to collect your bags, and proceed to the KLM counters for your next flight - of course to do this, you will need to land (pass immigration) in AMS as the baggage collection is after immigration.
For the second segment (AMS - CUR) you will need to show at the check-in desk in Amsterdam that you have the appropriate visas (or don't need a visa) to pass immigration in Curacao.
If your flight was DEL - CUR on KLM, then you would have no issues as they would check your bag directly through to CUR, print you two boarding passes DEL-AMS, AMS-CUR at Delhi, and you would be on your way.
The way the trip is setup, you have two separate journeys that are not linked together at all.
