Impurities on clothing and furniture

I live in a country where people openly drink and if my friends and all use my glasses and spoon after drinking should I consider them impure. I'm getting paranoid over this issue. Also if after drinking they have eaten or had drunk water and then they use my utensils will they still be impure. When we wash impure utensils in sink we usually don't see any impurity but it's just water that splashes from washing. Should we Consider that water impure. A dry particle from private part discharge fell on carpet. The carpet was dusted where that particle probably fell on floor The floor was then mopped.

Q: I am going through a dilemma. The thing is at my work place people eat haram food all the time. I have 2 co workers and the thing is I seen one of my co workers eating haram food and then he touched the phone that we use for our 24/7 work rotation shift. In about a month I will get that same phone. I saw his oily hands touch it after eating the meat taco. Should I wash the phone. Now just today he came to my desk and touched my mouse. Is my mouse considered napaak because with those same oily hands a month back he touched his mouse and all over his desk and then came over and touched my mouse. I figured this is all shaitaan so I just stopped worrying about it and left my mouse. But the phone is kind of putting me off should I wash it? It is a company phone I don't want to ruin it.

Q:

1. I suffer from droplet problem. After passing urine I wash and put toilet paper till all the droplets come out. However sometimes the toilet paper moves out of place. Does this make my underwear napaak and do I have to wash it?

Q: I have a problem with my stool passage. I don't know how to explain it but it gives of fluids without me knowing it also makes my clothes moist. Its such a thin fluid that when it exits I don't even feel it exiting. My inner garment is moist. I don't know how to attain tahaarat with this fluid and how do I perform my salaah. This fluid has a stench of stool because of it exiting from that passage. After istinjaah I dry myself and rub my hand across I still smell that stench.

Q: The other day I went to the bathroom to use the toilet and noticed a brown spot on the inside of my underwear. I am not sure how this had come as I had only passed stool the night before only, and after passing stool I had went for a shower/ghusl. In the afternoon around asr time whilst in the bathroom I noticed a brown mark on my underwear and found a mark only on the inside of the underwear. My pants was black so I could not see if there was a mark, I did check and found nothing. I had also checked the same spot on the outside of the underwear and it didn't look like any brown mark there but because it was material there was a slight smell. I had sat on many places during the day, some of these places were my car, rooms in an office, doctors office, home etc. Do these places become napaak wherever I sat? I am always very very careful with regards to istinja and as said I am not sure how this happen. It might have happened when I broke wind etc. Please advise urgently?
