Featured Japanese tea set. Please help with marks

Hello friends!
Recently got this Japanese tea set. It it hand painted, and there is a lot of saucers, cups, plates in it. All are a little bit different, so that’s the reason I’ve bought it.
I tried to find marks in catalogues, and I’m not really good in oriental porcelain - no success with identifying marks

Could you please help me with reading marks? There is two different marks, but pattern is the same. Any thoughts are welcome as always. Thank you!

 

Thank you!
And what do you think about this one? it looks different to me.

 

Definitely different, but I didn't find it (yet)

 

I tried to find that other mark with google lens. No useful result when GL-ing the complete mark, so I tried it with each character seperartely.

First character recognized as

Second

Third

 

I think the last character is 'sei' (made)

 

thank you, @Marote
I really needed that smile on my face.
