Tahaarat

Doubts with regards to tahaarat

Q: I went to the toilet and washed the front parts with water and I washed the penis first then I put tissue to hold it and then I poured water on the testicles and I don't know if I wiped the penis first then I adjusted the paper to told the penis and then pour water on it and the tip of the bath room jug touched the place where the paper was before when I was pouring water and holding the penis with the paper the paper got wet so I don't know if that part of the penis was napaak. When the jug tip touched it what should I do? I shook my uncle's hand when I came out of the toilet and I forgot to wash my hands and they were damp so would his hands be napaak and I held the toilet mop and will that be napaak as well?

Istinja after relieving oneself

Q: When I go to the toilet, I find it hard to wash my hands. I soap them then put them under the tap. Once all the soap is off I think the water on my wrist is impure still so I wash my arm from the elbow to finger tips and I keep doing that and still I have a feeling that my hands are impure even if I've urinated or past stool still I wash my hands like this and I use wet toilet paper 3 times instead of istinja.

Khilaal of the toes

Q: Regarding khilaal of the toes, should one make khilaal of the toes of both feet together after washing both the feet or should one make khilal of the toes of the right foot after washing the right foot and of the left foot after washing the left foot? What is the sunnah method?
