90 degree angle = right
fish=Spot (Spot being a fish). Given your clue last word seems to be 'on.'
'Right on' means 'Spot on', 'Bang on,' etc.
So my answer would be
Spot On

The plant Aaron's Beard is an alternate name for Rose of Sharon.

Not sure if this is what you want for this one.

2d availing

[Quizmonster]

2d is definitely 'availing'...anaesthetic initially is 'a'...'v' is the standard abbreviation for 'very' and 'ailing' means 'sick'...the whole thing meaning 'helping'.

[kettledrum]

Yes ont-ice - Aaron's Beard is definitely right - anag 'a border as an'.
