Bttv Twitch Emotes?

What can be understood by this or what exactly is meant when someone e.g. FeelsRainMan or pepeHands and all the other emotes in the chat?

So you seem to have installed the Bttv addon, you see these emotes and you just don't know what some of these emotes say? Since there are very many on Twitch in general, I would recommend google to you. But can possibly have different meanings depending on the channel.

pepeHands and FeelsRainMan mostly say grief in a nutshell.
