You don't have to be in BC to make models on Roblox. You simply select the bricks you want to make a model, and click the "Publish selection to Roblox" button. Then the window will direct you from there.
You have to make a model make it public domain and you can get it as a free model.
To make your own model, you have to go Build on a game. Make the model you want to make. Click the Drag button. Highlight it. Press File and Publish Selection to ROBLOX. Press Create and name it. Enjoy! ~9tailedfox21 (a.k.a. PrimalBlade or cloner6348 on Roblox)
You can use free model
There is no way to loan money to users on Roblox. There are no plans to make a loan system either. The closest way to loan people money would be to give it to them through donations (this only works if they have BC though).
No. It is not actually possible, and I don't think you can make donations, either. People spam and think it will work, but it actually doesn't. Robux is actual money in roblox in circulation.

First build whatever you want out of bricks in the Roblox Studio. Secondly, select all of the bricks you want to make into a model. Lastly, click the "group" button on the taskbar on the top of the window to make all the selected objects into a model.
You cannot insert models into scriptbuilders on Roblox. The only way you could would be if the specific place had a model insert tool in it. Also, some scripts that people make on scriptbuilders can insert bricks and can make it look like a model was inserted.
Most use a free model from the catalog
You can not make gear, but you can email the roblox people to make your own gear. (i told them to make a dance potion)
