I have a samsung phone can i add apple pay to my phone?

Per Apple: To use Apple Pay, you need:

• A compatible device1 with the latest version of iOS or iPadOS, watchOS, or macOS.
• A supported card from a participating card issuer.
• An Apple ID signed in to iCloud2.

You don’t have a compatible device. So, no. No Apple Pay.

Actually, Pay is an Apple exclusive feature with a biometric chip for processing payment.
