Water splashes on toilet seat

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.

Keeping good names for children

Q: Can we select some good name to name a child like that of a Sahaabi (Radhiyallahu Anhu) by ourselves or is it necessary to ensure that the given good name (like that of Sahaaba kiraam) is suitable for child. Actually, some of my friends say that even if you select a good name for the child, you have to consult a religious teacher who will check whether it is suitable for him, it should not be heavy on him, it should not affect his health or personality. Kindly clear this doubt.

Looking at photos

Q:

1. I wanted to ask whether it is sinful to look at photographs? Or can we can look at photos of our mahrams?

2. We are not allowed to look at non mahrams. Does it mean that we cannot look at him even at a glance for once? For eg. We need to see for once, so as to know who is our brother in law, or neighbour, uncle i.e. just for recoginition purposes. 

Sitting on a chair and performing Salaah due to back pain

Q: I am having some trouble in reading Namaz and I want some suggestions from you. I am suffering from back pain together with sciatica and lumber disorder (pain affecting the back, hip, and leg, etc.). Owing to which I am unable to perform sajda and rukoo smoothly in the traditional way. Doctor says that it is caused by compression of a spinal nerve root in the lower back at L4 and L5 etc. by degeneration of an intervertebral disc.). So, Doctor suggested to me to avoid standing and sitting for a long time, bending/leaning of the back, squatting, lifting weight, etc. as it will lead in worsening my condition. So, in fear of Doctors advice I am using a stool/chair in offering salat. My question is, am I doing the right thing or is there any way in which I can read namaz? Please suggest ways in which I can offer my Namaz on a regular basis without having to compromise my health.
