I think it's not a big deal to manage multiple wallet on one PC.It's totally depends on you,how much wallet you want to use or how much you want to save it on your pc.But one things is very important that is your security system.You should alwayes keep your wallet keys and also every information of your wallet in your own privecy.
We should know every time information about bitcoin and it's wallet privecy system and keep them yourself,thank you.
