I would try these options below in order, if you haven't already done so.
Contact the manufacturer or a retailer that sells that brand. There is a good chance they might fix them under warranty. I've had many good experiences with getting older equipment that you think might not be covered taken care of, but each brand varies on how far they'll go. It sometimes helps to go through a retailer to get warranty service.
The wide-mouth capped bladder may be compatible with a standard Nalgene-style lid, so if that's the one that only has a bad cap then try looking into that.
If it is the bladder with the narrow-mouth cap, then you can again try directly contacting the manufacturer or search for compatible caps by trial and error. I don't currently have enough detail to see style it is.
For the ripped bladder your options for self-repair are slim. Any glue or adhesive used would need to be safe for use with potable water and also remain flexible once cured. The cost of such adhesive would money better spent by putting it towards buying a new bladder. If the rip is due to age, then the bladder will most likely rip again in another spot soon after repairing, so it really isn't worth trying to fix it at all.
If all repair options are exhausted, you could use the outer insulating sleeve. Remove the old inner bladder if possible along with any extraneous parts such as caps or hose nibs, and simply slide in a new bladder with its own cap and hose coming out through a hole in the sleeve. You may have to cut open the old bladder to accomplish this and customize the old bladder sleeve to fit the new one.
If the outer sleeve has backpack straps, you could modify it be a very small daypack or cycling pack. Again this would involve some cutting and probably some sewing to achieve the end result.
In any case, I would think about what is the most practical option. If you can come to no other conclusions, you can recycle them and so at least the raw material can be used again.
