For the first two pictures... I think they're from Episode 128
... when Kagome comes back to her world because she has to take part in the cultural festival at school and Inuyasha follows her!
And for the picture with Inuyasha playing with Buyo, it may be from Episode 75
... when Inuyasha has a break in Kagome's world but then has to fight against the panther-demons! I'm quite sure because Buyo scratches Inuyasha's hand and Kagome's grandfather tells him that cats are revengeful... when Inuyasha and Kagome come back to Inuyasha's world, panthers appear!
