splashes

Q: I had the urge to go to the restroom (for toilet). Before sitting on the toilet seat I usually check the toilet seat whether there is any thing on it or not (I bent my back while checking). The moment I stood straight, I was confused whether from the toilet or normal discharge that gushed out. It gushed so much (this time I really had the urge to go). It was watery and I am confused whether it was from the toilet or clear discharge and that I put my clothes on the floor. I am not sure whether the impurity touched  floor or not. Should I wash the floor? It happened to me nearly three times. 

Q: When going on a motor bike after it rains, some water splashes come on to the lower side of my pants from the tyres, is it pure or impure? Can we offer Salah while wearing it? 

Q: I wanted to ask that when doing istinja sometimes the water used whilst washing may go on the toilet seat, either at the back or the front of the toilet seat, these can be splashes to drops of water. Are these pure or impure? Also when tried to wash the seat because of this, the water used to wash it then goes on the floor so does this make the floor impure and is it enough to wipe the floor with a sponge? Please help as I don't want to make the bathroom najis.

Q: I have a question that might seem self explanatory but theory had been a major fight in the family home concerning whether the spray from the toilet when the lid is open would make someone najis (dirty) if they sat down on it. Can you please clarify this as this has become a big issue with people leaving the toilet lid open and the flush makes a mist in the bathroom thus spreading microscopic particles and small drop everywhere. I appreciate your time.

Q: When I go to the bathroom, one drop of urine is sprinkled on the hand while passing urine. I washed my hand with water without soap. Is it permissible to perform Salaah and can recite Qur'an or else should I bath again?
