How to get form definition details by using the sitefinity A

Hi All 

I am working with the sitefinity 9. version. I am working with the sitefinity forms mainly in MVC. I am facing a couple of issue regarding the same.

1. Since sitefinity doesn't support the html form creation , how can i associate sitefinity form to my html  layout template  ?

2. While creating a web form i have seen that there is a provision to specify developer          specific names for each fields, how can i provide the same for MVC form?

3. Suppose i have created a form in sitefinity. How can i fetch the form definition details using Api along with their labels,limitations,fields, validation message etc(my intention is to create a custom mvc form widget where the field labels, error messages, limitations will be fetching and displaying in the widget so whenever any change in back end form definition that will get reflected easily in my widget)

Any help will be appreciated

Thanks in advance!!
