PROBLEM: Question: I am looking for a term to replace formulations like "the activities of the morning", "the rituals pertinent to the morning", "the morning report" (that one is from the Lion King, I couldn't resist). I tried perusing the internet search engines of my knowledge, including some searches on merriam webster's website, but I can't get a hold of what I am looking for. In fact, I will eat a better breakfast and pray every morning, now. 
Answer: I think I would use matinal, which the OED holds to have the same meaning as matutinal. However the latter they designate as now chiefly literary. The examples they provide, for matinal across three main senses, are as follows: = matutinal adj. 1. 1803 M. Charlton Wife & Mistress (ed. 2) II. i. 11 To attend the matinal dejeune's of old Gruffy in town. 1860 Ld. Lytton Lucile ii. v. 9. 30 The matinal chirp of a bird. 1862 Mrs. H. Wood Channings II. 74 Believing it could be nobody less than the bishop come to alarm them with a matinal visit. 1908 J. Davidson Testament 37 The earth with its seas and its skies, Its flowers and its matinal dew. 1991 E. S. Connell Alchymist's Jrnl. (1992) 100 Wounds contracted past noon are less auspicious than matinal injuries. a. = matutinal adj. 2. 1819 H. Busk Vestriad v. 276 The grey-ey'd Hours climb up the starry way To meet fair maidens matinal as they. 1842 F. Trollope Visit to Italy I. xiv. 219 As if my very matinal son and myself had constituted the whole party. 1997 Church Times 11 Apr. 20/3 I am, metabolically speaking, one of Bishop Heber's sons of the morning: a matinal man who is fast asleep before the epilogue. b.

SOLUTION: no

PROBLEM: Question: When it comes to cities and boats named after saints, it seems that "Santa" is always female and "San" is always male. e.g. Male Saints: San Diego, San Francisco, San Antonio Female Saints: Santa Barbara, Santa Maria So why isn't "Santa Claus" a woman like all the other "Santa"s? 
Answer: The city names you quote are all derived from Spanish, where "San" (or "Santo", as @tchrist clarifies below) is the male inflection and "Santa" the female one. However, Santa Claus isn't derived from Spanish, but from Dutch, where it was originally rendered as Sante Klaas, and was modified to Santa when it was adopted into English (and from English, to the rest of the world). Here's Etymonline's take on it: from dialectal Dutch Sante Klaas, from Middle Dutch Sinter Niklaas "Saint Nicholas," English, like all other languages, borrows words from many sources, and they often carry over remnants of their original grammar or usage, even when it makes for inconsistent usage in English.

SOLUTION: yes

PROBLEM: Question: If a possessive noun, which is plural, is preceded by "each", then should it use the singular or plural possessive form? For example, which of the following is correct? spend time in each other's presence spend time in each others' presence 
Answer: Surely it's always each others Each other is a (reciprocal) pronoun, so in its possessive case it becomes a possessive pronoun. None of the others: its, his, hers, yours, whose etc has an apostrophe. Adding one is generally seen as a sign of poor literacy.

SOLUTION:
no
