Changing a phone.

I would like to see what the S6,7,8,9,10 phones look like please?

These are all 'old' Samsung models.  Why not just use a Google images search?

I need the Baha 5 app on my phone to access things to do with my hearing aids. These are the phones that are compatible. It will not work with any other phones apart from Huawei P20 apparently.

The device finder & comparison tool at GSM Arena is as good as anything else, for this sort of lookup.
