Are these inks water soluble? Do they dissolve if they get wet?

I guess the question is how much wet, but mind has not gotten wet before

My L3260 comes with 544 ink, will these work? Can’t locate 544 anywhere

No, the loading heads are different.

Is this for the 5150 printer?

It is according to the Epson website ink finder.
