Isle of Wight finds - ID help needed

[cg.stefan.this]

Hi everyone!

 

I travelled to the Isle of Wight during the long weekend of April we just had and found some interesting things.

 

Everything below was found in the south part of Shanklin beach.

 

I'm sorry I did not include a scale in the pictures, but they are all around 10 cm.

 

Thanks for you help :-)
