Is there any way that I can control the loft, Make the loft go smoothly in one direction?
Same logic but some loft got error, and some doesnt….. why??

Help.gh is not a very usefull name on this forum. The title of your thread is very clear. so why not use it for your gh file, so I can recognize 
Loft sometimes gives strange results, it depends on how well constructed the input is. Pay attention to:
- curves gooing in the same direction (the option align sections will help there)
(it was the first I checked, and there was no difference, so the directions are OK. If not, use flip curve with guide curve to solve this before adding to loft). - curves what intersect might gave strange effects. I saw at least two spots where the lines are intersecting. Check/fix these and try again.
