There is some difference in usage between how about and what about.
If you are planning something with a friend and you want to raise some potential problem, you would only use what about- effectively as a short form for what shall we do about.... If you want to suggest a new idea or a possible solution to a problem, you can use either what about or how about.
Person A: How about/what about going sailing tomorrow! -suggestion
Person B: Nice idea, but what about the kids? - potential problem
Person A: Could we get somebody to baby sit?
Person B: How about/what about your neighbour's daughter? - suggested solution
Looking at your sentences:
what about/how about her? -if she's a suggestion or a solution
what about her? - if she's a potential problem.
.
What about/how about playing cards? -playing cards is a suggestion
There are 3 scenarios in total: objection, suggestion and caring about. You would only use what about in first case. "How about/what about" are interchangeable for other two situations.
Let's say A and B are discussing the vacation.
A: How about/what about a vacation to Hawaii? (suggestion)
B: Great idea, but what about the dogs? (objection, potential problem)
A: My parents will look after them.
When the friends are Hawaii, they drink a lot at party.
A: I am so drunk. How about/what about you? (caring about, asking about what someone is doing or feeling)
