Do these limitation exist for Lex?

Question

I am new to using Amazon Lex engine and I have few questions to better understand its limitation since I couldn't find anything related in the docs:

1. Do amazon's Lex support composite entities? If so reference or example.
2. Do amazon's Lex support taking any value that the user gives, for example if I'm taking the users feedback I want to let him say anything even if it's a troll or meaningless answer.
3. Can Amazon Lex take in lists, for example, if I want to give multiple names having 1 simple prompt for the name won't do it I want a list prompt is that possible?

EDIT: 1-There are 2 names slot types AMAZON.DE_FIRST_NAME AMAZON.GB_FIRST_NAME, one that supports names most commonly known in great britain the other for german, i need the composite entity feature to combine these 2 slot types into one entity.

2- I simply want to take the user's input exactly as it is, it may be sbfhbf or my feedback is none of your business or whatever it might be.

3-Let's say i asked the names of the people on the dinner table in a restaurant i want the names of everyone , currently i'm using amazon.gb_first_name and i'm only able to take in 1 name and actually print it out.
