Touch nahi, but I can recognize hands I guess. Like if you observe closely you can make out ki kiska haath hai. For example, if a person had habit of chewing nails then unke nails bahot hi chhote hote hai, birth marks, moles, scars etc bhi hote hai, length of fingers kisi ke middle finger is remarkably tall than other fingers, kisi ke index finger ke length ke hote hai. But yeh sab dekhane ke liye closely observe karna padta hai
To some extent yes
Hands are recognizable...it is somewhat easier I think...the people which are around us regularly, like parents/siblings, some friends, unke hands recognizable ho jaate hein ek time ke baad
