Hmm, I'm going to have to agree that the vine is a variety of honeysuckle.

The juniper is either too dry (needs watering) or if the soil is damp, then rootbound. So check the soil first, if it's fine, then you may need to repot it.

The dianthus , if placed in a well protected area over witntrer, should come back just fine the next spring. Most here, if well protected, will come back.}:)
