Showing duplicate product

You shouldn’t be getting duplicated products.
Are you using the slider ?

yes, I’m getting same products displayed under related products. please check my website choose almadina from the filter and open country chicken, on the single product page you can see the duplicate

I get 4 products, no duplicates.
I am checking this:
https://tajhalalmeats.com/product/country-chicken-copy/

PFA – I’m not sure why this happens randomly

Need to restrict showing random display

Ah you mean you getting the “current” product in the related section.
But that’s not the case as you do have duplicates into your database it’s normal to get them in related.

ie you have:
https://tajhalalmeats.com/product/country-chicken/
&
https://tajhalalmeats.com/product/country-chicken-copy/

you should only have 1 of those.

yes, you are correct.

Is there any way to hide the current product being displayed in related products as they belong to different tags

https://tajhalalmeats.com/product/country-chicken/ belongs to almadina

https://tajhalalmeats.com/product/country-chicken-copy/ belongs to Halal store

customer can purchase only one store/tag products at a time, so it will be good to have only same tag products under current product

Normally that shouldn’t be happening.
Maybe there’s a theme conflict it’s really hard to tell without a local installation.

Both belong to the same WooCommerce store, the store you are referring to i guess is a theme feature that “groups” the products for checkout and shipping rules.
Unfortunately that doesn’t effect the queries.
