The first question you need to ask yourself is, Is there any reason why I have to play the tunes in any particular key, including the key in which they are written?
You might answer yes if you want to play the music with another player who wants to play them from the music, or to accompany a singer whose range dictates the key. In this case you might need another whistle - see later.
If the answer is no, then things are very simple indeed as far as which whistle you need. Any whistle will do! Although you may have to transpose the tunes, which might be more difficult.
Any whistle will do because you can easily play in two major and two or three minor keys on any whistle.
Your D whistle for example can easily handle D and G major, and E and B minor, plus A minor with a little half-holing to get an F natural.
(It can also handle E dorian and A dorian easily, and B dorian with a half-hole - these are older minor scales widely used in Irish and older European music.)
So, if you have a D whistle and the tune you want to play is in a major scale other than D or G, you’ll want to transpose it into D or G major. Which one you choose will depend on the tune’s range - how far above or below the tonic (main note) it extends. If the tune’s range is only an octave or so then you can play it in both keys.
Same goes for minor keys - on your D whistle you need to transpose into E minor, B minor or A minor depending on range.
Now, most whistle players think “D and G” whatever whistle they are actually playing. So once you’ve transposed the tunes into D and G, if you want to play them in the key in which they are written, you can then choose the appropriate whistle.
To cover the keys you mentioned, plus a few more:
An A whistle can easily handle A major (“D” fingering) and D major (“G” fingering), plus B minor (“E minor” fingering), F# minor(“B” minor fingering), and E minor (“A” minor fingering).
In the same order, a C whistle can handle C major and F major with ease, plus D minor, A minor, and G minor.
To play easily in E major major you’d need a whistle either in E (“D” fingering) or in B (“G” fingering).
Hope you can make sense of this. In many respects it’s easier to play by ear!

Hadn’t seen Jessie’s answer when I wrote this - she says it more economically …
