Good morning.

I've purchase (used) some 2 gallon Chemical "jugs" with spouts like the Arkays.

I keep my stock, non-dilluted, in 1 gallon "brown" jugs but I'd like to dilute and keep my use chems in the large jugs. These have the floating lids as well.

So, how long can I keep my chems in my darkroom, cool dry space please?
Dev, fix, stop, hypo etc.... I use a vary of Dev's.

Thank you much.

Look on the data sheets for the products you are using. In general the diluted solutions don't last very long, at least for developers. Usually, working solutions are used immediately.

Yes.
When I worked in a commercial scale lab we had 5 gallon floating lid containers for film and print developers and fix. These contained stock solution that was diluted for working solutions as needed. In the printing room we used 20x24 trays that probably held a gallon or two at least.
For individual use they are probably overkill unless you run quite a lot of material.
