The writing on picture #6 is 於浪華囗囗囗 ← the last one may be 正 or 柾. It should be the smith's name, but its too obscure for me to make out. I was thinking maybe 村正 or even 古村正, but neither of these are viable candidates.
The other side is a dedication to the person who ordered the sword, who appears to be Kojima Masamichi (小島政道) but the rest of the dedication is a bit cryptic for me. There is a date of 元治元年之秋 (Autumn 1864).
大府保衣 would be the name of a person or class. It says he gave money for this (sword).
(Another possibility is that 保衣 is a miswriting of 褒, i.e., 大府褒賜銀為之, meaning "大府 gave money as a prize for this (sward)".)
The kanji after 元 are 甲子 Kinoe-ne, but the year is 1864, anyway.
