Help... Stalled Transcribing Sheets, About Tempo And Tuplets (Probably)

Hi, recently i was transcribing to understand how to use sheets, i made some of them already with no problem, but...
Recently was transcribing 3 pieces, and 1 of 3 i stalled 3 of them lol.
Unfortunately i only know the basics of music theory, and never had any lessons (and i compose with softwares that aren't needed any knowledge for sheets)
To make it fast i cut the part of the pieces that im having problems. Anyone willing to help this fellow?
 

Problem 1
This piece has Harp, Violin section and a Piano, violin has the same issue as the piano after, the only difference is trill and accents with staccato, then probably wont need help any futher with this piece. Then
*Please if the Harp notation is wrong tell me
*How should i transcribe to sheet this bizarre tempo?
*Do i need expressions because the tempo?
*Is it the tempo anyway? idk
Update:
Recently was reading about tempo and seems the piano is in rubato but still a little confused how should i transcribe the melody on sheet
how i notated bellow is ok? or is kinda off? should i change 3/4 on piano to another?

Audio file is attached

The another problems i will post after if needed. Since probably could be the same problem with the rest of them.
Thanks for Reading, Any help will be appreciated.

Put a brace on the grand staff instruments. Use A minor.
Harp: Split the quavers into tied semiquavers, then beam four semiquavers on each beat.
Piano: Indicate tempo rubato and write in straight rhythm. Use an acciaccatura for the first E and subsequent short ornamental notes. The arpeggio should be written before the affected notes instead of after. If needed, provide a literal interpretation in one bar for clarification.

Oh! Thank you very much. i didn't know about Acciaccatura, and at same time i took some time to read about ornaments and learned about "Appoggiatura" and "Turn" that was the other issues from the others pieces.
By the way, looks much cleaner now with semiquavers on harp, and grace notes on piano.

Thanks for the help.
