First of I can see you spent a lot of time on thhis suggestion however multiple suggestions shouldn’t all be in one suggestion.
This is a cool concept maybe check out [Warning: Mammoth Suggestion] Hive Honeycoin - YAIGC as it is a similar concept to what you are suggesting.
What direction would this go or would it be like the fire book in SW?
These have been suggested here, also here, and even here. 
these are for water buckets in each gamemode
For adding ladders there is only a suggestion for ladders in tw which you can find here (click me)
I feel that this would make Hive similar to other servers and not have its own uniqueness as Hypixel already has enchanting.
This is a cool suggestion but some people might get really annoyed as you can easily get hit of a bridge.
Cool idea maybe but you should create another suggestion for this individually
I don’t really have an opinion on this
This could be a really interesting maybe it would send a firework that explodes so your teammate can find you but also other players so it has risk and reward
this would be a cool idea especially if it is intractable and you can eat it and it respawns after an a bit for the individual that ate it
I don’t think that daily gift/ weekly gifts should be a thing 1. Because this can be a lot of work for the designer, 2 they occasionally have daily gifts such as during Christmas the last two year you were able to earn a gift each day.
**For suggestion that don’t already exist you can make a suggestion individually so that people **
