你好吗？= How are you ? You can speak it to strangers and friends ..... 最近好吗？ You can only speak it to someone you know . It means " how 's everything going ? or how are you doing ?. If you speak 最近好吗？to a stranger , he might think 你认错人了。

actually, i guess there is no native chinese speaker will use "你好么" to mean "how are you", at least, i have never used it in this way, and if someone said "你好么" to me, i will doubt wether s/he is a native chinese speaker. i always say "你好" to strangers, if i have to start a talk, and to friends,i will say "最近怎么样"，which means "how are ya doing" or "whats up"

"你好吗"equals "How are you ?" "最近好吗"equals "How was your day" OR "What's happening?"

no difference. the meaning : "how are you?" or " how's everything going?"

你好吗=how are you ? 最近好吗=how are you recently ?
