These are generic musical terms (of which there are many more).
And roughly the subset seen implemented on synths.
Arpeggio

Arpeggio is the concept of breaking a chord into notes in quick succession, often specifically one ordered by increasing or decreasing tone.
You may associate (particularly slower) arpeggiation with seventies and eighties synth sounds,
because arpeggiation was both
a way to get chord-like things out of often-monophonic synths,
and an easy way to something that functions like a bassline.
Wider than that, it can be an intentional technique in composition.
Vibrato
✎ This article/section is a stub — some half-sorted notes, not necessarily checked, not necessarily correct. Feel free to ignore, or tell me about it.
Vibrato is a regular variation in pitch.
Tends to be a small and fast change.
Used in singing, and in various instruments, often for
a fuller sound,
a more emotive sound,
for a spacier sound,
for more permissive pitch perception,
etc.
From a synthesis perspective, it's frequency modulation with a small amplitude (typically less than a semitone) and fairly slow(-for-FM) carrier.

Tremolo

A trembling effect.
This can come either from
- very rapid repetition of a note
- sometimes for the perception of it being played longer
- sometimes for the texture that the variation in volume gives
- a (often fast) variation in volume.
Sometimes confused with vibrato,
which makes sense in that on various instruments (and e.g. a Leslie speaker) the two come hand in hand, due to physics.

Ornament
Ornaments are notes (improvised, marked, or marked with some interpretation on how to play)
that are not necessary to the melody, harmony, or rhythm (in the analytical sense),
but still add to the piece as a form of decoration.
