Second, three of my planets, the moon, saturn and mercury fall in the last part of a house. Many people told me to consider them as if they were placed in the next following house, but I strongly feel them in their "canon" house, especially my Moon. What could be the reason? Am I in the wrong?
As per your birthdata and your birth time given on vedic section - your TOB is very precise and looks accurate.
Some astrologers would consider a planet sitting close to a house cusp into next house. (I pers. don't do) But mathematically - and astrology is about mathematic details- a planet is where it is. Your moon is on 21°21'45"taurus and your ASC is on 22°18' taurus. Your moon is mathematically still in your 12th house - if you feel your moon more up there- you are right.
With moon opposing pluto you anyway have a very intense and very good intuition and also prewarnings a fine antenna for instinctively knowing "more" and to get aware about more - also a prewarning antenna for danger- if you listen to. As a moon in 12th house has the most highest outlook in a chart for perceiving future events coming - more than others are able to do with having their moon in 1st quarter of the chart and under horizon.
Your pluto is on 22°44'22" scorpio short after DC on 22°18 scorpio and noone would consider it back to 6th house. Your pluto is in 7th house. Facing and opposing a moon in 12th house - not yet "from this world" - like hesitating in the very last minute at point of birth -to get physically born and to "jump into a physically female body". (moon rules 3rd house - a phyiscal body house -where people can notice you and your body appearance)
And this subconsciously stored birth experience will accompany you -whenever you start a new beginning in your life. Needing some time in every new-beginning - with hesitating.
Your mercury is sitting exact on you IC cusp - between two houses- kinda in the doorgate of 4th house cusp - house of siblings and 4th house - house of own mother - looking like a mediator between both house themes. Between two signs- female cancer and male leo.
If on looks at orbs and their validities an astrologer uses himself as being effective- saturn squaring moon is of 6° orb- I wouldn't see as effective and valid anymore. Saturn square pluto a slow mover- for me isn't strong and effective neither.
But sun square moon - sun square pluto - sun at apex is an intense t-square you are dealing with - from birth on. Sun rules your 4th house - mother as first female model role and own gender support for a woman- mother experience in childhood and already before birth- during pregnancy.

Your chart looks like your mother and father would have more preferred to have a son for their family and ancestor line - 8th house - ruled by jupiter. Jupiter squaring your venus as your ASC ruler.
Mars as prenatal 12th house ruler sitting in intercepted virgo -mercury ruled - in a main sun ruled male principle 5th house - sextiling leo mercury sitting between 2 houses.
You afterwards probably took a subconsciously impression from - that something must be wrong with your body and that you have to daily work on it and to earn your right of physical existence and to feel yourself entitled to be here on earth - venus as your birthenergy and asc ruler squaring libra jupiter as 8th house ruler- in 6th house- work - ruled by venus, too.
