input: Write a function to extract the latest stock prices from specific websites for a given list of stock symbols using web scraping techniques. The function should accept a list of stock names as input and return the latest stock prices as output. If a stock price cannot be retrieved, the function should skip that stock and continue with the rest. If the input list is empty, the function should return an empty list.
