hi,

I have (in my garage on a wooden shelf) 2 times 1l 7% H2O2, 1l 37% H2O2, 1l concentrated H2SO4, 2 small plastic bags with KI and KNO3 and a bottle with 800g KHCO3.
The plastic bottles concentrated H2SO4 and H2O2 are both in separate plastic containers.

They are on the same shelf where I keep my organic fertilizer.

Is it ok to store like this?

I would keep H₂O₂ and H₂SO₄ as far from each other as possible on the shelf, they seem to me like the only potentially dangerous combination.

OK
one question which might be a bit stupid...

When I have an empty bottle of H2SO4, there is of course still some H2SO4 on the sides inside  the bottle.
Is  it ok to poor water in such a bottle to clean it?
It will not give any splashing?

Minute traces of chemicals always adsorb on surface. Eventually use  very dilute bicarbonate to neutralize traces of sulfuric acid.

Ah ok,
So I can wash the bottle with KHCO3.

...

I would think that NaHCO₃ might be less expensive.

@AWK
I think when @Tex said

...

a thought was given to the rule to add acid to water and not adding water to acid.
I am assuming that in this case the cleaning process adds so much more water than acid that the heating is diluted out.
Other wise how would we clean glassware that once contained an acid.

I have KHCO3 as fungicide
I use it on my tomatoes.
