A:AnswerNo, I don't believe so. The grip can handle regular phone sizes up to the size of Samsung Note. Samsung Z fold phones have longer width.
The grip is detachable so try to shop for a grip that can handle bigger sizes. I believe there are some that can handle sizes of an iPad.
A:AnswerI believe it is structurally sound enough to hold an iPad but the Equipment Clip that comes with it is only able to hold a Mobile Phone due to its size. It uses a standard Hot Shoe Mount I believe so if something is found that will attach then there would be no issues with supporting an iPad.
A:AnswerNot without a different adapter. The tripod itself has a typical threaded mount (like for a camera)... the included adapter only works for smartphone-sized devices.
A:AnswerYes, it works with any camera with a tripod mount (or you can use the cellphone holder for phones). It holds up to 3kg, so as long as you don't have a large lens it will work.
