Your toilet may be backing up due to a clog in the pipes. This can happen from flushing items that shouldn't be flushed, such as paper towels or sanitary products. To fix it, you can try using a plunger to dislodge the clog. If that doesn't work, you may need to use a Plumbing snake or call a professional plumber for help.

Your toilet may be backing up even if it's not clogged due to issues with the plumbing system, such as a blockage further down the line, a malfunctioning sewer line, or a problem with the toilet's internal components. It's best to have a professional plumber inspect and diagnose the problem to determine the exact cause and provide a solution.
The drains for the shower, toilet and sink all connect to a common line. Assuming the toilet is not backing up, the problem indicates that there may be a partial blockage, enough so that some of the toilet flow is backing up through the shower drain line. You need plumbing repair. The shower leak you mention should only be in the shower, or else you have a broken drain line as well.
You should get your drain lines snaked
I would suggest getting a plunger and some draino to clear out the pipes.
Your kitchen sink may be backing up due to a clog in the pipes. To fix it, you can try using a plunger or a drain snake to clear the blockage. If that doesn't work, you may need to call a plumber to help with more advanced solutions.
If your plumbing system is properly installed there should not be any problem. If it isn't installed properly, you would already have water from sinks and bathtubs backing up out of the downstairs toilet.
Actually No, a Goldfish cannot swim back up the toilet. The construction of the trap (the "hole" in the bottom of the fixture) prevents water from backing up into the toilet (see links for a picture). the only way this might be possible is if the toilet is clogged. (the water can't go down the drain and overflows)
Your basement drain may be backing up due to a clog or blockage in the pipes. This can happen from a buildup of debris, grease, or tree roots. To fix it, you can try using a plunger or drain snake to clear the blockage. If that doesn't work, you may need to call a professional plumber to assess and fix the issue.
