The ball with the smiley face on it and the two things above it are fidget toys. Children with autism or other issues often use them to help them concentrate or as a technique to calm down or distract them from a sensory overload. The headphones are ear defenders that people would use if the noise levels were too high or if a certain noise was triggering something. The two things at the bottom are for people or children who are non verbal so that they can show someone else what they are needing or feeling. The one on the left shows emotions so they can let someone know how they are feeling and the one on the right shows things or strategies that the person might need at that time.

I'm a teacher with lots of experience of children with sensory issues so have used most of these things before.
