I had a bidding accident in a recent bidding practice and wanted some opinions.
What do you think should the following auctions mean?

1C - 1S; 1NT - 2H; 2S
1C - 1S; 1NT - 2H; 3S
1C - 1S; 1NT - 2H; 4S
1C - 1S; 1NT - 2H; 2NT - 3H; 3S
1C - 1S; 1NT - 2H; 2NT - 3H; 4S

1C is artificial and forcing
1S is 4+ with 8+ hcp
1NT is GF (guarantee 16+ hcp) asking for further description but not part of a relay structure
2H is natural and deny a minimum (show at least 10 hcp)
2NT does not promise or deny any specific shape

Over the 1S response opener had available to him 2NT as 4 card GF raise with shortness, 3S as 4 card GF raise without shortness.

I believe those are all the relevant agreements but feel free to ask

Thank you for your help

For all 2/1 players please consider the following auctions:

1S - 2C; 2H - 2S
1S - 2C; 2H - 3S
1S - 2C; 2H - 4S
1S - 2C; 2H - 2NT; 3H - 3S
1S - 2C; 2H - 2NT; 3H - 4S

2C is an absolute GF and denies a 4 card GF spade raise.

How about this all with 3 spades support 2S all round strength with slam potential consider whether 4S or higher or 3NT is the best contract, 3 S strength unbalanced tell me about your shortage (in clubs or diamonds high slam potential if the right shortage), 4S low slam potential- no aces and missing one queen continue with more than 2 aces.

for me:

1) slam try in spades, 3 card support.
2) never had this one.... maybe splinter in s agree h, 4h support, confuse pard..avoid this one?
3) responder has dead minimum gf with3s, otherwise many play picture bids.
4) spade cue...agree h, again try to avoid this one? I think 2nt showed d stoppers.
5) 4S WOULD BE kickback ...rkc in h.
