1. Pass. Sure, we 'might' have a diamond partial but we might well have nothing at all. A lot depends on the inferences available from East's pass of 2♠. However, West's pull to 3♣ suggests that he has 5 spades and 3 clubs (with a constructive hand), and was afraid his partner might play him for Jxxxxxx or so in spades, and have passed 2♠ with shortness. If so, then opener could have 4 spades, and now we may have no playable fit. Btw, having a gap between the top of your 1N and the bottom of your 1♣, especially a 1 point gap, seems sub-optimal. May I suggest 14-16 1N and 11-13 1N rebids?
2. A double is attractive, especially at mps, since partner will often be able to convert, but it is top-bottom bridge, and I am not a fan of rolling the dice even at mps.
3. 4♥. Style counts.....as someone who has played a lot of weak notrump, I love opps who make wide-ranging natural overcalls....my belief is that the range for overcalling a weak 1n should be the same, if not stronger, then that over a strong 1N.
4. Pass. When we double a weak 1N, and partner pulls.....he is WEAK. A useful rule of thumb is that he should be passing with all 5 counts, and a lot of 4 counts. Once in a while they can make, but let them work it out. This is an area where I am happy to roll the dice, because in my experience, the opps often get it wrong.
5. Pass. I think doubling 2♥ for takeout was insane, fwiw. As the auction suggests, it may well be that one of your sides best fits was in hearts....but don't worry....LHO was never passing 2♥ anyway, not if he is bidding 2N (!) over your value-showing takeout double of hearts.

Hand 1.
OK, my actions may be questionable up to this point, but what now? Double now would be penalty
IMO, Pass = 10, 3♦ = 7.
Action is fraught when you know so little about partner's hand.
