Help Identify Switzerland Stamps

These are stamps in my collection that I've not been able to identify and value. Anyone?

The first group are officials. They were issued in different years (up to 1962) and can be told apart by the size of the dotted circle and the date of use. There are some better ones; please give us the circle measurements and let us see each one and we can identify them.

The second stamp is from 1912, the forerunner to the Pro Juventute series of semipostals. There are 3 different colors. This is the commonest, worth a couple dollars hinged.

Last one is a charity "stamp" (forerunner of pro-juventute stamps)

Per request I have posted separate photos and info regarding the Officials here: https://goscf.com/t/65308

Thank you for your help, fellow members.
