Retirement tax questions

Just to clarify, I'm not in the same plan as my wife, we both have separate insurance and separate HSA accounts.

Shouldn't the limits be calculated separately in this case?

 

For me, I was covered on single HDHP all year. I contributed $4300.

For my wife, she was covered on single HDHP half the year and the other half on family HDHP. She switched her plan after we had a baby, but I'm still not in her plan. She contributed $8550.

No one is over 55.
