Twitch has an ever-growing list of emotes, way too many to show and update here.

There are also subscriber emotes, which a streamer can set up to give to subscribers.

Bit cheer emotes come in 5 tiers, Twitch Bit Cheer Emote 1 Bit 1, Twitch Bit Cheer Emote 100 Bits 100, Twitch Bit Cheer Emote 1000 Bits 1,000, Twitch Bit Cheer Emote 5000 Bits 5,000 and Twitch Bit Cheer Emote 10000 Bits 10,000.
There are also many other skins for cheers that have different graphics and animations.

Third-party emotes are a thing too, and can only be viewed using BetterTTV or FrankerFaceZ.
