I left the tree in full sun, inside. How do treat this tree to recover?
First, I would move it to a shadier location. Then, if freshly scorched, wrap with moist burlap or saran wrap to slow dessication. When bark finishes dying, trim off dead tissue. Keep roots moist and insulated. If only foliage is affected, you can try trimming off the dead/dying foliage. If it's severely burnt, you may not be able to revive the plant.
I received a bougainvillea bonsai, delivered by UPS. There is a bag of loose pebbles included. Am I supposed to put them around the stem and press them into the dirt?
They may have meant for you to use them as a mulch (on top of the soil) or for drainage (below the soil). If the bonsai already came potted, then it was likely for mulch.

I have a maple bonsai and it's still a seed. I'm doing the thing where you put it in a brown paper towel that's wet and place it in your refrigerator and in a zip lock bag. I have the fertilizer I want to use for it but I'm not suppose to "feed" in the first month. By "feeding," do people mean giving it fertilizer? Or giving it water, sunlight, and carbon? If it's the fertilizer (which i think it is), then what do you plant the seed in once it starts to sprout? I can't put it in a pot of fertilizer, so what do I use? Normal dirt outside? Cause that doesn't sound very healthy for very delicate plants. So my question is "what dirt do I use to plant my seed?"
Yes, feeding means to fertilize your plant - a balanced fertilizer should work fine. As for the soil, try regular potting soil.
I have several Trumpet jade plants and some are getting spongy. Am I watering too much, which has been about once a week or less, not until the bonsai soil is thoroughly dry.
You may be watering too much, as jade plants require very little moisture during the winter months. If this is the case, you may need to repot the plant into a container with fresh, well-drained potting mix. Be sure the pot has a drainage hole.
Lack of light may also be a factor.

Can I start a potted bonsai tree by taking a seed or trimming from my pomegranate tree? Is there a tutorial that could help me?
Typically people use dwarf pomegranates and train them to be bonsai trees because the height of dwarf varieties is usually no more than 2-3 feet - also, it might be easier for you to work with as a beginner. That is just an F.Y.I. and something you may want to consider.
I was, however, able to find you a tutorial online on how to create a bonsai from a pomegranate from the early beginning stages:
http://www.bonsai4me.com/Basics/Basics_Growing%20Bonsai%20From%20Seed%20page1.html
You can propagate pomegranate trees from seeds or from semi-hardwood/hardwood cuttings. Just keep in mind that this is a slow method to cultivate a bonsai because it normally takes 3-5 years before a tree can be trained.

Want to know the minimum distance to be kept from an L-shaped building while planting five ten-year-old bonsai banyan trees into outdoor soil. I have two buildings in L shape. The place needs shade badly. What is the minimum safe distance I can keep when planting the banyan trees?
Banyan trees can get too large for planting anywhere near buildings. That said, even though these are bonsai plants, planting them in the ground will only allow the roots to grow and spread, so I would suggest leaving the trees in containers - you can use large planters if necessary - to prevent any issues with the roots later. If you must plant them in the ground, I would leave at least a 20-foot spacing from the building.
