Impurities

Q: Will clothes with najaast become pure if washed in the washing machine?

Q:

1. Once after urinating some drops came and I touched it with my hand which was less than a dirham. At that time I assumed it to be water and ignored but now I think it was urine and with this same hand I touched the water bottle and I didn't wash it. Since then when I fill the bottle with cool water the outer portion also gets wet and my hand too, so was my hand najis all the time and I might have touched other objects after the hands got wet. I also might have prayed salaah in this way. Will my salah be valid? At that time the impurity was less than a dirham, but due to filling the water as the outer portion also gets wet, will the impurity spread and exceed the size of a dirham and make me najis as well?

2. I get a lot of waswasas about purity and about many other things. Please tell some effective ways to fight these waswasas. I try to ignore but I fail.

Q: There were very small tiny spots of madhi on my undergarments (very much smaller than the excusable diameter) and when I make istinja the front organ is wet and touched the area but nothing got onto me so as the impurity was of excusable amount can I regard myself as pure even after the wetness from my body touched that area?

Q: I went with my family to a family friends event while I was there. I don't think I thought of anything inappropriate (sexual) not that I know of. When I came home I used the bathroom and when I was washing myself there was a lot of discharge but I don't know if it was because of thinking about something inappropriate at the gathering we went to. I washed 3-6 times. There wasn't a lot of discharge on my underwear just the normal one. Am I napaak as I don't know what it came from? If I am using my phone and sleeping on my stuff is it now napaak? Are the fancy clothing I wore their napaak? There isn't any discharge on them?
