No, they are the default SL animations applied to all avatars.
Likely from your scripted mesh body... Animations with UUIDs are the ones played by scripts on your avatar; these can be one-shot animations (llStartAnimation() & Co), or animation overrides defined by scripts (llSetAnimationOverride( ) & Co) and the latter may keep playing (since they are overrides to SL default animations), even after the scripted item has been removed (if it did not call llResetAnimationOverride() on detach event), or stopped.
You may stop externally started animations in the Cool VL Viewer with "World" -> "Stop animating my avatar", the scope of the latter feature being configurable via the "Preferences" floater, "Cool features" tab, "Animations" sub-tab, "On 'Stop animating my avatar' ..." check boxes.
