Hi I am a newbie and I am planning to invest ETH coin but I only have limited amount of money to start investing. Can I buy less than 1 ETH?Your response are greatly appreciated.Thank you. 
Yes, of course. That is great of you to plan joining even with a minimal starting investment into ETH. Do not worry, that investment of yours will for sure grow in value over time. Perhaps you could reach the 1 ETH within a couple of months.
