Hello

Id like to buy a VPN account so that my traffic is safe.
Im not a technician, so can you please explain it to me:

1.) when i use a VPN connection from a  reliable company from inside a internet coffee,
- can the network owner see my traffic?
- can people within the local network see me?
- can the provider see my traffic?
- can the VPN server owner (whatever company that may be) see my traffic`?

Basically, if a use a encrypted vpn to a service provider (paid!), is someone able to see my traffic?
when i download torrents?
