My Bananas do not fill out all the way to the tip. Do I cut the pod off while they are still ripening or wait for the harvest?
The best way is to harvest the bananas as they ripen. They ripen from the back to the tip, so the tip will be the last to ripen. Some of them may never fill out, so some gardeners to choose to cut the tip of the flower off early on, when the small bananas are just starting to form. Most leave it alone, though, since it doesn't really offer that much of an advantage.
In whole, it is up to you. Cutting the flower improperly can lead to rot, or failure to fruit, however. If you are in doubt, it will be best to leave it alone.
Another thing to consider is that most of the bananas will ripen close to the same time, so many times it is easier to sacrifice the smaller fruit and cut the whole bunch at once.

What do I feed a banana tree?
During the growing season, it will need a fertilizer high in nitrogen. During the blooming season you will need to increase the amount of phosphorus and potassium, while decreasing nitrogen.

Have the wrong plants planted around our pool & would like to know about planting frost tolerant Basjoo Banana Trees.
They are the most cold tolerant and should do fine in zone 7. In fact they can withstand temperatures in zone 4.
However, they do need to be covered with mulch in winter. Here is how:

My banana plant has wilted after reporting help should I use John Innes no.2 soil? Also I have other banana plants with black spot; what is the best anti fungal treatment for this please? This photo was taken a couple of days a go but much more wilting has happened.
No I believe that soil would be too nutrient rich for the plant. It sounds like they all have the same underlying issue, though... overwatering.
Make sure that your container has plenty of drainage to allow all extra water out. They should never be allowed to remain in fully saturated soil.
Make sure that the soil dries out completely down to about 3 inches before watering again. If the container has no drain hole then you will need to let it dry out almost completely down to the bottom between watering.
You will want to treat with a fungicide as well. These articles will help:

My banana tree bloomed and formed bananas in mid-July, but the bananas are still not mature. I cut out all the suckers and cut off the bloom. What else should I have done?
It can take 3 to 6 months for the fruit to mature. (Also be sure you have a variety with edible fruit. Some don't.) You will cut them down before they turn yellow.
Here is more information on fruiting:

From Botswana, Africa Sandy soil Drip irrigation
This will, usually, occur from fungal/bacterial infections. This is caused by being overwatered, or remaining too wet for too long without a chance to dry out some in between waterings.
A fungicide will be useful, here. This article will help you with fungicide use: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
My cat has been urinating in a large banana plant. Do I need to repot and change all the soil or can I flush it out by overwatering it several times? Any idea on how to get him to stop using the plant as a litter box?
It should not be necessary to repot the plant based on that factor alone, although it is beneficial to repot and upsize the container with new potting soil every couple of years. From the photo this plant appears large for the available soil volume.
Flush the soil to leach excess salts from the urine as you suggest.
Our experts suggest placing a kitty litter tray or pile of sand somewhere in the vicinity. The cat will much prefer the sand to the potting soil, as long as the sand is not wet.
Another alternative, or to be used in combination, is commercial or homemade cat repellent in the plant container.
