Seeds are growing inside the banana fruit. Is there any way to stop it and have seedless banana?
Not unless you plant a commercial-type banana like the dwarf Cavendish. Commercially grown hybrids have had the seeds bred out. Wild type bananas have large seeds.
This has been a confusing topic to research for me. We bought a house with an established banana tree. I do not know if it has fruited in the past so we cut it down last December when we moved in. It grew back but did not fruit. What should we do this year? Its about 7ft tall so it stays outside. There are also several pups so I need help figuring out what to do with it!
It likely didn't fruit previously. Bananas need 10 to 12 months in a frost free environment to flower and fruit. You did the right thing in cutting it back. Here is more about their care:

You first need to find out what type of banana tree do you have as some do not bear fruit. Ornamental banana trees come in various sizes but most do not produce edible fruit (a few develop small, sweet edible bananas). In areas with mild temperatures during the winter, banana trees survive without damage from freezing temperatures. Tropical banana trees will bear fruit, propagate via suckers from the rhizome (horizontal underground stem) and then die. A local plant nursery may be able to assist identifying the cultivar that you have.
My newly purchased cavendish banana plant has some brown spots and the leaves are kind of curled under
It is likely a fungal disease. Here is how to help:

I've had this plant outside in my yard in FL and it's never really done well at all. Should I maybe dig it up and just keep it in a pot? It's still really small. Now the roots are coming to the surface and poking out. Advise me please on what to do.
Do you know what is causing the roots to come to the surface? Are you watering deeply? If you are only surface watering, it could be the roots are searching for water. Try watering them deeply about once a week, which will encourage deep roots.
They do prefer moist soil, but it must be well-draining. Make sure it is sited in a well-draining location. Here is more:

We cut the banana trees back to about 12 inches in the late fall
If you are hoping for bananas, do not cut down the pseudostem. If the outer layers are dead, you can remove those, but if there is living tissue in the center, the new growth will come at the top of that.
If it is soft and mushy, cut it to the ground and it may come back from the roots.

Several plants have some dark streaks also. They are planted in the ground
This is likely a disease from overly wet soils. Be sure to treat with a fungicide, and let the soil dry out down to about 3 inches or so between waterings.

The front of my leaves are very green and beautiful but I noticed underneath the leaves are a light brown and I don’t know what could be the problem I only fertilize it once every 2 months and I make sure not to over water it can you help me
I can't tell from this photos whether that is webbing or fungus, though, spider mites can lead to infection just as well. Fungicides can help, but you may want to apply a miticide just in case.
