I’m wondering if iwatch in cellular mode(not in bluetooth mode or connected to the wifi) can receive Whatsapp or any notifications when iphone is not connected to the internet

no, meta(facebook) never made a apple watch app for their whatsapp service

the only thing you can use the watch for in terms of whatsapp is to receive the nonfictions,
so the watch will not ring or be able to receive calls, even if the iphone is available and online
Can Apple Watch with cellular receive WhatsApp messages when iPhone is offline?
