Get multiple numerical values using Forms

I am new to RASA. I need to design chatbot which will interact with user and collect various numerical information related to Age, Salary, location(Pin), etc. along with some text information (name, email, etc.). I am using RASA forms to do this task and train the model to extract those entities. I am able to fetch text information and one numerical value (location) using rasa forms as I trained the model with respective entities and add those values to respective slots. But I am confused about how I can train my model on various numerical fields as each numerical entities are similar to each other. If I didn’t train the model on each numerical field, I won’t be getting all slot values and form will not finish. Is there any way such that we define only one numerical entity (ex. NumberEntity) and reset value of that entity after every question which will have numerical response.

Duckling is a good choice for numbers. There’s a blog post on entity extraction here.
