They may use a light tent, but if they are, it's still quite directional lighting. These are shot for cut out, and shooting for cut out rarely involves a light tent, and often use all manner of scrims and flags to tightly control the reflections and highlights. It's hard to say exactly how they were shot. To get results like this you'll need studio lighting, some space to build a suitable set, and a camera capable of full manual control (especially if you are using flash).
You're forgetting one thing you'll need though... skill. Good still life and product photography is not as easy as it looks.
If you have none of the above, it may actually be cheaper to find a photographer local to you who can do it for you as I get the impression you are not one yourself, nor experienced even at a hobby level.... as you only came here to ask that question.
There is no one answer that will give you what you need. You need studio lighting, a camera and lots of practice... but read some books...
This one, and
this one will get you started.
Essentially though, you're asking what you need to do in order to get results like those who have years of experience, but with no experience or equipment. Photography doesn't work like that.
As for your question about photoshop, yes, it has been used to "cut out" the product as the set originally would have had all manner of crap there... little black pieces of card to add reflections, little white pieces of card to bounce light back into shadows to reduce contrast etc. These shots were not made by just putting a phone in a white light tent. Most shots for cut out rarely are. Once the set is built, then yes, it's a production line to an extent, but some changes may have been needed for the darker covers.
These would have been shot lying down, yes, but lit to make it look like it's standing up when rotated, so that needs skill, great understanding of lighting, and perspective. There's no way they are stood up.... too slow and fiddly to be repeatable quickly.
If you have no experience with photography, or interest in it, and just want quality commercial shots, consider finding a local photographer who can do this for you.
