Can I use a usb type c card reader in my MacBook Pro 2009 as the card slot is no longer working ?

Sure you can… but you’d either need a usb-c to usb 2.0 ( A) adapter or just buy a usb 2.0 ( A) card reader and use that.. here’s a link to a usb-c to A adapter: https://www.primecables.ca/p-399618-pc-da-cc0017-usb-30-a-male-to-type-c-female-converter-fast-charging-superspeed-data-sync-black-primecables… plus you’d need to buy an external usb-c card reader… or just get an external usb 2.0 (A) card reader which are around $ 25 with shipping( usually less) … vs usb-c card reader plus adapter plus shipping which is more than $25… obviously #2 is preferred…
