PROBLEM A: Pass
PROBLEM B: 4 Clubs
PROBLEM C: Pass
PROBLEM D: Pass
PROBLEM E: 5 Diamonds
PROBLEM F: Yes | 5 Diamonds
PROBLEM G: 3 Spades
PROBLEM H: Club 10

First ideas, may change one or two

A. Pass going for a plus better than a partial
B. 4C A good suit worth showing it now
C. Pass same as A.
D. Pass maybe i can show minors later
E. 5D
F. Yes/5D If that 4NT bid is not rkc i change partner
G. 3S but i miss Gazzilli
H. C 10  seems the best shot at not giving a trick

Problem A  5D. I’ve seen a lot of 4-4 contracts with a 7 card side suit go down

Problem B 5C. Pd must have a play for 5C. With an 8 card suit it could be cold

Problem C 3S. Not afraid to play 4S opposite a singleton

Problem D 4S. Let pd know slam is on the radar

Problem E 2H. with 2S the D ruff shortens dummy and there it goes the chance to profit from the long Hs

Problem F 4NT. what else as yleexotee says

Problem G No 6C for me. So the question is how many tricks will East make. With H AQJ seventh and S KQJ he will make 8. But with that holding he might bid 4H. So he has 6 Hs and if he has S KQJ9 the S 10 will prevent the 8th trick. So by a narrow margin Double over 5C

 Problem H D K. perhaps I can play C K later C K lead can give a trick

Misread problem G but I will stick to 2NT
