Can anyone help with what these are? Another loft find!

The first two are British helmets I believe, but other than that not a clue on the date or use.

Other than knowing that of the rest one was picked up in Thailand, the Somme and one has a Swedish coat of arms I literally know nothing about their origins.

Anything that can be useful would be much appreciated; era, type, country of origin, value if any etc.

Cheers in advance.
