On a standard Bb trumpet, the fingering for C is open.
On a standard Bb trumpet, the fingering for a bottom-line Eb is 12 and the fingering for all higher Ebs is 2.
A double-sharped note is just raised two half-steps from the original note. So if you have A##, the first sharp would go to A#, which is the same as B-flat, and the second sharp would be the A##, which is the same as B-natural.
d sharp right above middle C is the same as Eb -- 2/3; the D sharp above that is 2.
E sharp is F natural, so, 1st valve.
open valve

valve 2 and 3 down
1 and 2 for the one on the bottom of the staff open for the one on top

It's the same as F-natural
Not sure exactly what you mean by the question, but in general, for written music purposes, an E flat is the same as D sharp. On a b-flat trumpet, E flat is fingered as 2-3.
