Ma'zoor making new wudhu for tawaaf

Q: I am leaving for hajj in a few days time insha Allah. I have a problem of continous discharge. I am maazoor.

1. If for example I am travelling and I stop to read zohr namaaz. After reading my zohr namaaz can I make a new wudhu immediatley with the intention of asr or do I have to wait for the next salaah time to set in and then make a fresh wudhu?

2. Can I just make a fresh wudhu before every namaaz without changing my panty liner?

3. After performing salaah in the haram do I have to make a fresh wudhu before I start tawaaf?

And what happens if for example I am performing tawaaf and the time for the asr sets in, do I have to make a new wudhu for asr salaah and after performing asr salaah do I have to make a new wudhu again to complete my tawaaf?

How many times should one wash impurity off one's hands?

Q: I want to ask that if one's hands are very dirty e.g. if urine drops can be seen on one's hands then how many times should the hands be washed. Beyond that limit of washing, will it be a sin. I'm asking this because I'm getting mad day by day as I wash my hands for 20 to 25 times with soap, so it very irritatating to wash so many times as I'm not getting satisfied that my hands are now clean.

Wearing a cloak that ties above the waist

Q: Is it permissible for a woman to wear a cloak that ties above the waist, STRICTLY in front of Muslim women?

Here is an explanation: A belt that ties above the waist will make the cloak a bit tighter towards the top part of the body, it will not be loose fitting on the upper part of the body. However, the lower part and the navel to knees will be covered without showing the shape of the body. This will be strictly in front of Muslim women (e.g. a function). Basically will she be exposing her satr (her satr in front of Muslim women) in this situation?
