Your plant in picture 1 does not have enough detail for me to ID, but I'd guess Agapanthus. If so, poisonous.
Plant 2 is "pothos", as others said. Not dangerous.
The palm in the 3rd pic. may be an "areca" - Dypsis lutescens - not dangerous.
Fourth is a Dracaena 'Warneckii' - not dangerous.
Fifth is also a Dracaena, or possibly a Cordyline. Not toxic.
The 6th, a Lantana, should probably be considered a danger, and removed. It may continue to appear from fallen seeds.
Your last plant in pics 7-9 is likely a Xanthosoma, or perhaps a Colocasia. These will appear on poisonous plant lists, but rarely actually cause problems with animals.
