Question About YouTube Ranking

Hi, just wanted to ask two question someone who know:

- Can It affect something (ranking or not suggesting videos etc..) if I use 3+ different YouTube channels (different gmails) and upload videos from same IP?
- Is good to combine buying two types of YouTube HQ High Retention views: one from external and one from suggested? Or its just better to leave it from suggested?

Thanks!
