When you cast a spell that targets only one creature and has no rank of self, you can spend a number of ritual points equal to the level of the spell to target a second creature in range with the same spell (1 point of ritual if the spell is a cantrip).
This spell protects a consenting creature that you touch and creates a mystical connection between you and the target until the end of the spell […]
The spell ends when you drop to 0 or if you and the target are more than 20 meters apart. It also ends if the spell is cast again on one of the connected creatures..
No, you can not (or should not) use this spell with a paired spell. In Warding Bond, it is written:
& # 39; It also ends if the spell is again launched on one of the connected objects.
Considering you are one of the connected creatures, it would end with the first target and then reform on the second target (if you had to use it with a paired spell).
With the comment of @ Blckknght, it would be possible to select several targets with the spell as long as you are able to fulfill the requirements (touch the targets, pronounce the spell and use two platinum rings to launch them).
Here's where it's difficult because the spell requires platinum rings to be worn by the caster and the target, but since the spell is not thrown againyou do not use another pair of rings to bind to the second target. Because you need each target (and yourself) to wear a ring, with the basic rules, it does not seem possible to cast the spell correctly. If you were to talk to your DM and work on a situation of 4 rings, the spell could be cast "correctly".
