According to my limited understanding of the above sentences, the sifaat Al Khafa belong to the letter ha, and all the madd letters (alif, ya and wow).
For all the madd letters, it's called such since their pronunciation is hidden when it comes after any letter.
For the letter ha (deep ha, before the letter ya) the sentence implies that the sound of ha is somewhat subtle (in between its weak sifaat and strong) if one finds it to as a dhomeer (pronoun) and is read in wasl (continuance; that means, you don't stop at it, which obviously the sifaat of al hams and ar rakhaawaah would supersede)
Secondly, mad ma'nawi is a bigger category, a contrast of mad lafzhi (comprises of all the mudood: from mad asli to mad laazim kalimi, etc).
It's pertaining to the meaning of a word, especially the word Allah to amplify its meaning, even though many authentic reciters do not agree with this rule. In fact, madd ma'nawi is being used mainly in du'a and the athan, where the pronunciation of Allah is longer than it should.
It's also used in kalimah tawheed.
Allah knows best.
