Yes, condoms are not 100% effective. Read the label on the box.
Not unless you had no barrier when you ejaculated into her. If you had the condom on and ejaculated into the condom while you were inside of her, then exited her and changed condoms (unless the condom broke) you could not get her pregnant. The only way for her to get pregnant is if you ejaculated into her or emptied your fluids into her (and most condoms have spermicide). If neither are the case, it is nearly 0% chance that she could get pregnant.
yes if it is on the outside and you wont if it is on the inside
YES
Your penis will be covered in urine.

Yes. If she doesn't want to get pregnant, then ALWAYS use a condom.
yes.
It makes no difference in or out of the shower while having intercourse; if your not on the pill or not using a condom, it is usually east to get pregnant.
If any sperm are anywhere near the vagina, you can get pregnant. I have a 30 year old to prove it (no penetration).
While using a condom it is not possible to get pregnant.
of course. the birth control pill is very effective if taken correctly. there is always room for human error, so yes there is a chance of getting pregnant while being on birth control and no condom use.
