All q-bids for me...

#1 is obviously not clubs because you could pass the dbl. It shows 10+ with major 4-4 or any GF.
#2 same as #1
#3/#4 are usually defined as 3-card limit raises, but #3 could be a general force without support. Hard to picture #4 without support, but I guess it could be.

1.
(1♣) P (P) D
(P) 2♣ ?

Cuebid - With ♣ you can pass or bid NT. If the last bid suit is the suit you bid, it is always a cuebid.

2.
(1♣) P (1♥) D
(P) 2♣ ?

Natural. ♣ was the suit that could not bid before AND there is another possible cuebid. 2♥ would be the cuebid.

3.
(1♣) P (P) 1♥
(P) 2♣ ?

Cuebid. ♣ is the last bid suit by the opponents.

4.
(1♣) P (1♦) 1♥
(P) 2♣ ?

2♦ would be the cuebid since
* ♣ is the only suit that could not be bid earlier.
* ♦ is the last suit bid by the opponents.

Ditto Gerben, exactly as explained.

I agree with SoTired, all are cue-bids.

In the second example, one should bid 3C with real clubs.

How does it work when they bid 1NT ?

(1♣) P (1NT) D
(P) 2♣ ?
and

(1♣) P (P) D
(1NT) 2♣ ?

(1C) P (P) D
(1H) 2C ?

This is a cue. When partner makes a double which is for take-out of a particular suit (clubs here), a bid in that suit is always a cue. Bids in other suits are natural even if the opponents have bid them at some point, so a 2H bid here would be natural for example.

(1C) P (1H) D
(P) 2C ?

Although this double emphasises spades and diamonds, for the purposes of deciding which bids are cues I think you should think of it as being take-out of the last suit bid (hearts here). So 2C here is natural and 2H would be a cue.

(1C) P (P) 1H
(P) 2C ?

Since the opponents have only bid one suit I would probably interpret this as a cue.

However the natural meaning is also useful. If you're playing in a really serious partnership I would recommend using 2D as the cue here and 2C as natural. [More generally: when RHO opens 1 of a minor, you pass and partner overcalls in a major, use a bid of the other minor as a cue. This is particularly useful when playing against a short 1C or Precision 1D. If you had a hand worth a natural bid in the other minor then you would normally have overcalled on the first round.]

(1C) P (1D) 1H
(P) 2C ?

This is definitely natural; 2D would be a cue.

A nice idea - auctions after balancing are still a very undiscovered country.

(1♣) P (1NT) D
(P) 2♣ ?

Natural. Again, strong hands just double. It's just possible that we have a 6 - 1 fit in ♣ (opps having 3 - 3 or so).

(1♣) P (P) D
(1NT) 2♣ ?

Natural. Strong hands double.

This goes as far as:

(1♥) p (1NT) X
p (2♥)

Although this will be rare, if you have a weak hand with a solid sequence in opener's suit you might bid this. For example:

♠xx
♥QJT98x
♦xxx
♣xx

Worth 4 tricks in ♥, zero in any other strain.

Changed first example:

1.
(1♣) P (P) D
(1♥) 2♣ ?

Natural. Double would show ♥, as would 2♥.No real cuebid is available here but that's okay since I couldn't bid over 1♣.

Elianna and I have the following set of rules on this:

(1) If only one suit has ever been bid naturally, then bidding the opponents suit is not natural.

Therefore in the following auctions, the 2♣ bid is artificial (primarily asking better major):

1♣ - P - P - X; P - 2♣
1♣ - P - 1NT - X; P - 2♣
1♣ - P - P - X; 1NT - 2♣
1♣ - P - 1NT - 2♣

(2) If partner has bid a suit naturally, then bidding one of the opponents suits is not natural (except that raising partner's suit is natural, even if the opponents bid this suit also).

Therefore in the following auctions, the 2♣ bid is artificial (primarily a raise of partner's suit):

1♣ - 1♠ - P - 2♣
1♣ - 1♥ - 1♠ - 2♣
1♣ - P - P - 1♠; P - 2♣
1♣ - P - P - 1♥; 1NT - 2♣

However, in the following auction 2♣ and 3♣ are both natural:

1♣ - P - 1♠ - 2♣; P - 3♣

But the 2♠ bid in this auction is artificial (primarily a raise of partner's suit):

1♣ - P - 1♠ - 2♣; P - 2♠

(3) If partner has never bid a suit naturally and the opponents have named at least two suits, then bidding an opponent's suit is normally natural. However, there are exceptions when passing would normally allow us to defend the same suit doubled, or when opponents have bid and raised a suit.

Therefore in the following auctions, the last bid is natural:

1♣ - P - 1♠ - 2♣
1♣ - P - 1♥ - P; 1NT - 2♣
1♣ - P - 1♥ - X; P - 2♣
1♣ - P - 1♥ - P; 2♥ - 3♣

However, in these auctions the last bid would be artificial:

1♣ - P - 1♥ - X; P - 2♥
1♣ - P - 1♥ - P; 2♥ - 3♥
