What is the minimum amount I need to copy trade?

There is no minimum amount of deposit required. However, we do recommend an
initial deposit of USD $250 to ensure that you have sufficient funds to manage your risk.

If I open an account and deposit less than $250, will I still be able to open and copy trades?

Yes, you should be able to still open and copy trades if you deposit less than $250 into your account.  However, is important to take into consideration the trade specification.
